Pretty simple question, which one is better? TruTech or Phass? I am planning to replace my tube driver with one of those options. For TruTech, i'll go for T03 or C7 and if Phass, i'll go RE or HP. Please help me to chose guys... thx...

I've never used Phass but I own two Tru Technology amps, and I'm very happy with them.

Perhaps ask Mr-Bob, he has first hand experience with both manufacturers.

well i've got an HP100 and HP475 sitting in my room. i've also heard a Tru T2 200 and T03 2 400. (with BB upgrade)
wen i fire up the HP amps i'll give you my opinion.
the HP series amps use all 1% hand picked components, the HP100 is dual mono (from what i can tell)
i expect them to be of similair quality.
the RE amps don't have alot of power, but sound incredible will probably compare with your tube amp for sound and output (if it's real tube, not hybrid)
the output transformer amps (Phass RE) have alot of the "tube characteristics"

i think you will be happy with either. I used to own 2 tru tech amps and even though they were the lower range ones the build quality was amazing, i can only imagine what the C7 would be like

For me the best amps I have seen so far have been Tru Tech.

.

I have been using a Tru Tech T-03 2.250 with the Burr-Brown upgrade for a few months now on my front stage and it is easily the best amp I have used and the all-around quality of everything about it is the highest order.
Can't say better than that, superb product, and a definite step up from the T2.200v2 which I now use as a sub amp.

That said...... having seen the Phass HP amps that Mr_Bob has, if the quality of presentation and finish is anything to go, I'm real keen to have a listen. The high-end Phass product is simply gorgeous stuff.
The Phass Alnico range high-end speakers have finish in the "to die for" range of things....

All that is code for "you are looking at some choice stuff there, henrysutrisno"

Tru tech? Where can I get them, any show room here in NSW.

Henry: In Sydney Fhrx stocks Tru Technology.

For my opinion, TRU Tech is a better amplifier compare to PHASS. It is not because I own the T03 but then I have audienced both amps recently. Eventhough both amps have their own potential, but I still prefer TRU Tech as they are much more mellow and much more powerful than any of the Phass amplifiers (even though Phass has a Tube characteristic and I love Tube amp).

BTW, is the burr brown upgrade is recommended??? or just stick with the standard T03???

Sonic Nirvana aka Critter has the Burr-Brown upgrade on his T03, perhaps send him a PM

Thanks... I'll do that...

Do you know what is the different before and after the burr brown upgrade in term of sound quality? As I am already more than happy as it is.

I can only guess, I haven't had any first hand experience with the upgrade. It would be subjective also

Talking about the upgrade to Burr Brown. Is the upgrade on the OPA? Which model do they up grade too? 2604AP or 2604BP? I have a offer on a C-7, wonder what kind of Burr Brown upgrade in it. How this C-7 amp sound? Anybody know? Ultim8DTM5 if I were to use Tru Amp does that mean I am in TEAM TRU TECHNOLOGY AUSTRALIA?

This is what John Yi had to say on the ICIX forums Tru Tech specialist forum:

"Our standard chip #TL072 is in all of our amps except for C-7
The BB (Burr Brown) IC Chip will offer you this:
It tends to improve Mid-Vocal. Meaning, the mid-vocal will sound more focused, transparent and will push back the mid-range's soundstage further back into the dash."

The C-7 comes with B-B input chips as standard fare, the option is an Analogue Devices chip on this model, which has a different "sonic signature" again.

My understanding is that the factory has to do the upgrade so you pretty much have to order the amp that way from Mo.
I haven't heard two T-03s with and without and ordered mine with B-B coz the above sounded like what I was looking for.....

i think you should just flip a coin or see which would look better in your car, cause thats the only difference that either of those amp's is going to make.


please ppl remeber it's a car..

Yes its an unofficial club but your Tru amp will automatically be your entry ticket





Yeah its difficult to find when the law of diminishing returns actually kicks in, but remember there's people who deaden their Camry's entirely in Plain Chant and have $300,000 hifi at home. Car audio might be a cheap alternative in comparison? I dunno I can't fathom it either.

i don't have first hand experience with phass but Tru Technology is an excellent amp and I love working with them. I don't think you will be upset either way you go!

I guess that means I am in Tru Tech Team? !!

...James

Gee... that is one hell of a ticket... LOL

So it is not possible to do the BB upgrade for T03 unless I am ordering one with the BB upgrade. Is that what you guys are saying? Dang!!! that means i wouldn't be able to audience T03 with the BB upgrade. BTW, if there is a pro technician would that still be impossible?

It probably would be possible but remember you would be voiding your warranty because the technician would not be an authorised Tru repairer (Tru themselves)

I can't really see how you would be able to do back-to-back testing without the assistance of a Tru dealer. Sorry

Dang!!! I know the TRU Tech distributor in indonesia pretty well... he doesn't even know if we can order T03 with BB upgrade... LOL...

I'll talk to some technians during the holiday. If they think that it is pretty easy and they have confident in doing it, probably i'll have a go... I'll let you guys know if it works or not...

I think it's just comparing apple and orrange. Apple got a its sweetness and orrange is likely to be more sour than an apple. Some people would say that Tru Tech is better and Phass is better. Instead of asking it to everyone, I think u should give it a try on both. They both are very genuine made amplifier. So there is no wrong nor right answer to this question. Is just a matter of personal preference. U should listen to both of them and decide it for your self. But I'm bit confuse with your taste dude. From Butler - Arc - Now u want to go to this diferent amps.

I have audienced both amps and I just need people opinion about them. IMO, TruTech is a more powerful amplifier and more mellow. Don't get me wrong coz Phass is an awesome amplifier, its just doesn't suit my taste. With Phass, I think i need at least two of them or maybe 4 to run my system... LOL

I like to try many different kinds of amplifier. The reason being is not to compare them but day by day, my ears becoming more sensitive. I found lots of negative point about Butler and ARC. But so far, TruTech is the best amplifier that I have ever heard in my life. I would like to try the New Audison HV Venti. The problem is $$$$... the price is just too crazy...

what about the zapco range of amps, in particular the reference series? how do they rate compared to the tru tech and phass?

I knew it. Your ear start becoming really expensive now. That's why I don't to listen to your car. I'm worry that after listening to your car. My ear will start becoming really expensive too. Hahahaha

Go for it dude.

Can't really compare Zapco with TruTech or Phass... Price wise is just too different... and if you take a look at the component that the TruTech and Phass use, you'll know that zapco isn't the right competitor for them... IMO

so your saying the tru tech and phass are much better amps? ive had a look at the prices of both of these and zapco. for dollar per watt the zapco are more affordable. is there such a difference between them that they warrant more costs? cheers.

The problem with alot of people is (i must confess i was one of these people) that they worry about what other people think and what is the most expensive equipment out there on the market. I myself have thrown an enormous amount of money into this hobby and still now find myself disatisfied with my current system, this is mainly due to the fact that i listened to what other people said and not listened with my own ears. I am now in the process of re-building my system for the third time in 12 months and i now one thing for sure i will be putting my hard earned cash into what my ears tell me sounds the best. So all i can say is listen to your ears and not worry about how expensive things are and if they are a brand name or not.

I think you are contradicting yourself a little Archie... no offence. Your new system you are building is IMO primarily based on what is the most expensive in most cases, and what others have told you is the best. How many times have you asked me, what is the best xxxxx, regardless of cost etc.?

I think you had a damn good system there, and scrapped 75% of it without even getting the most out of it, simply because you have been around MUCH higher end equipment. We've seen it a few times now (ask Henry) where you spend $$$$'s to get what sort of return? Henry has admitted spending a lot at times for no audible difference.

Can "you" hear an audible difference between Audison/Stinger/Phoenix Gold top of the range cables compared to Audioquest? I think most probably not, so why the upgrade?

Sorry, don't mean to get you offside... but I just don't think even you agree with most of what you said in your post?

Tru-tech vs Phass..

Well, I'm not a fan of the RE and I'd prefer a T03 or C7 over a HP, so I guess that puts me on the Tru-tech side of the fence.

At the end of the day, both these amps are considered high class, in theory, and dictated by their component make-up, and their marketing. No one can say which is a better amp, and unless you start talking features then they are the exact same amplifier to all your senses except for your hearing.

Let your ears be the judge, or if not possible to compare both look further. Cost, Cosmetics, Components Used etc.

The only way there could be a correct answer to this thread is if someone had done a back to back test, and only then it would be subjective and not something anyone of us could argue with. For me personally, the cheaper one would be the better one

As i said, i to was guilty of doing this in the past, but have come to the realisation it dosent matter what you or any people say, its most important to listen to as much equipment as possible and make my own judgement. The fact that i do respect your opinion and certain other peoples is the reason that i ask for peoples preferences in products so i can use them as a base for what products i should look into auditioning. I may be contradicting myself but iam saying that i am aware that i have done that in the passed and i now realise that before spending any more money i will be auditioning as much as possible before making any purchases. It could be that my next amp could cost $50 or $5000 i dont care, but my point is that i have learnt that my ears are the only ears that matter and thats how it should be for everyone and im just trying to help some people into not making the same mistakes as i have in the passed. Whether you or other people think im full of it that is your opinion as this is mine.

cheers

Hey dude, never for a second did I imply you are full of it Don't jump too quick

My point to that post was... you were asking a lot of questions about specific products on these very forums, and then virtually overnight the products listed for your system in your signature changed. How you had managed to audition all those products overnight was what suprised me

Its all good

The "best" flavour of the month on these forums is not always the "best" :thumb:

Well you all know where i sit. There were times when it was a hard call deciding whether to marry Amelia (my wife) or a TRU C7... sometimes i still wonder if i made the right call...

Good Call.... The C7 is surely pretty looking, but without being able to audition both... I can't make a comparison

Well the RE series are technically different - they have one questionable spec. I guess this could be considered a feature, but I do not want that feature. Also, using a normal hi-fi amplifier would give you a bit more flexibility - you can fairly easily match a normal hi-fi amp so that it sounds like the RE series, but it is a bit more difficult to make the RE series match a normal hi-fi amp. Thus I would choose one of the alternatives over the RE series.

Just my opinion of course. :wink:



Looks like a match made in heaven.

Yeh, i sometimes find it a bit inconvenient her power supply connection port isnt large enough to accept my 4/0AWG cable tho...

Well, audible different in different Amp, H.U or Pre amp. Which sound better? I woundn't dare say which sounds better, they are all good. What I mean is all the top of the range H.U or any equipment.

Audible difference in them? Yes they are, the different is the sonic signature in them. Like Pioneer P-9 and Alpine F-1. They are totally different. P-9 is very open and very detail and it sounds airy to me. Some people prefere this kind of sound, some people don't prefere it. Just like me, I like how F-1 H.U sound the way it is. A Burr-Brown sonic Signature.

In all the competition I had participate, I upgrade everytime. Actually I had all my gears in hand sinces June, I just want to try all of the stuff one by one. To find out any audible different. Sometime yes sometime no, I have to admit. I have upgrade almost everything from H.U right down to the last the speakers. All In order, yes all in order, no jumping here and there.

The biggest different during the upgrade is 2 thing that i had done. First is the RCA cable from the H.U to the Preamp, before I was only using the Rockford twisted cable then I change it to audioquest SKY RCA. That was the biggest jump in sound. A full silver cable with silver termination is totally different compare to a copper RCA, like the Rockford I am using then.

Well like Marc says back to back testsing, well in my car it always ready for this test sinces Melbourne GL Pro. Because my Preamp has 2 input and my H.U has a RCA out which is modified by me. Just a switch in the Preamp you can compare it instantly. No delay and no cheating. The result? Have a listen and keep it to yourself. I don't want any nuclear war in cables

Secondly is the pre-amp it use to have AD opa in it. It sound good, but only at entry level. So just for the sake of it I change it to have a compare of how is it like with Burr-Brown. I change it to Burr-Brown ap series opa. Sound good, but too mellow don't really like it. In the end I change it to A/D top of the range mono block opa. It sound just the way I like it. Fully transparant with very good mid detail. I even have Burr-Brown BP series 2 time the price of the current AD mono block and still waitng to be tested but didnt went ahead because I like the way it sounds by the AD mono block opa.

Just like Tru tech amp they have option between AD or BB. They are totally different in sonic signature. Both sound great but with different taste, Like it or hate it. Thats all in my point of view.

can anyone else vouch for this? id like to know whether there would be any difference in sound?

Reply to blitzmile:
It actually depends on what sort of splits that you are using... As my experience, the zapco amp is dry... and the price is close the Audison... and I prefer Audison more than the zapco... BUT, IMO Zapco will suit the dynaudio pretty well...



I have to agree that cable make ALOT of differences in sound quality... but I'm not sure about the silver cable... IMO, the silver cable is dry... it definitely not suit the Butler amp (coz i used to run silver cable by A&T and Kimber)... I was thinking to upgrade my RCA cable into Cardas and Speaker cable into Tributaris flat wires...



I changed my system a while ago Marc(coz I have problems with my Tube Driver... i got pissed and change a lil bit of my system)... and I just changed my signature recently as well as my headunit... sorry about the mis-understanding caused...

I do agree some silver cable are dry, but most of it don't cause this problem anymore. Good choice using Cardas for RCA. Why don't you try audioquest cheetah they are very good. Try Chord from U.K, Rumor 4 or Oydessy 4 easy installtion 100% teflon very tough but strip the outer teflon. Very well constructed pure copper, heavily coated with silver in the outer layer. Result TRANSPARANT!!!! Very, very impressive with the result.

Hi brother, can u tell me what's the problem u have with ur tube driver ?

I'm not sure if i can get CHORD in Indonesia... normally the SQ enthusiast using Cardas, Van Den Hull and Kimber Cable... but i might try to get the CHORD if not from indonesia, maybe from singapore... BUT, the question is THE PRICE... expensive??? how expensive???

Not to worry on the price, they are only entry level from CHORD, but very well constructed. They even have some review on them at entry level cable. They are selling for $40 to $50 a meter in Australia for the odessy 2. Not that expensive if you can get it from Singapore.

LMAO, is that actually a picture of yourself and your "woman"?


Oh, and does she have any "sisters"?

Reply to audioquest:
See if i can get 'em from singapore... nobody mention this brand before in indonesia... usually normal installation they use stinger or monster cable... and for pro installation, normally tributaris, cardas, kimber and van den hull... Thanks for your input...

If you do a search on ECA, there is a test with the Tru and Phass amps done at Image Dynamics.

From memory that test did not include Phass, but Tru, Brax and Sinfoni
