Does anyone have any experiences with the Tru Technology C-7.4T (tube Amp)? How good is it compared with other SQ amplifiers on the market? Does tube amps make a lot of difference compared to non-tube amps?

Cheers!

[mlim3]

Seems like Tru Tech amps aint that popular...

[Reza]

It is popular, but then the price aren't, very few people can afford that particular amp. My advice is to try out the amp yourself.

[Pyroay]

Tru Tech are very well regarded but are quite expensive and hence are not as commonly used as some other brands, particularly the C7.

henrysutrisno is a member on here who has just got one. Try a search on it and get his feelings….

[Kev]

Yeah I love my Tru Tech but have never heard the C7. I would say that they are popular seeing as a lots of rich people have them in their cars. I think their was a Lamborgihni or something with a few in it?? But yeah how many people on this forum have a car like that Ask about Jaycar and you will get a lot more responses simply because lots of people can afford them.

Not sure about the tube series of Trutech... but what i have experienced in tube, they are not road friendly... the tube is quite fragile... i used to have Butler Tube Driver and I took it off because problems with the tube and it cost me AUD300 to replace them. However, TruTech might have solved this problem tho... usually tube amplifier is not as powerful as any other amplifiers... but it procuce a very warm sound... i took butler as an example eventho it is not a fair comparison... butler 2150 produces 2x150watts... and i used it to run Dynaudio MW160GT... i compare the result with ARC2100 and ARC is much more powerful... the musics are more live...

I have 4 TruTechnology amplifier so far... T1 4.65, T03 4.150, C7.4 and Hammer H1... and i love all of them... The T series are a very american characteristic amplifier as they are very powerful, detail and bright (not as bright as those ARC Audio)... IMHO to have a better result, i wouldn't recommend you to use Alpine or Pioneer headunit... Eclipse, Denon and Nakamichi are hightly recommended to pair with any TruTechnology amplifiers... it would give detail, neat, warm and mellow result...

I just installed my C7.4 in my car a couple of days ago... so i can't really give a short review regarding it... and I'm still working on the passive crossover... All i can say, C7 is more to european characteristic... When it comes into TruTechnology, you can't go wrong even with the T1...

What do you mean by not road friendly? and it's quite fragile? Is it due to the bumps on the road?

[heimerich]

yup... due to bumpy road... i didn't know that until i bring the butlers back to Indonesia where bumpy road is one of our cultures... LOL...

Maybe its your lowered car with the big rims.

Get a 4wd and dodge all the bumps. lol

LOL... it might be one of the factors... but it was before i put big rims and lowered it down...

[ultim8DTM5]

From memory, Tru Technology do not use Svetlana tubes that Butler use.

[heimerich]

well, if so then problem is solved (maybe)....

Any recommendations on what speakers would go best with the C-7.4t? Since you said it produces a very warm sound, should I be looking at speakers that are able to produce a warm sound as well? Thanx!

[heimerich]

Depends on your budget tho... I like the one that is attached in my car but i'm not too sure if you have it in Australia... it calls Fabulous Acoustic... there are 3 version... the most expensive is FA1 (USD1650), FA3 (USD750) and FA2 (USD550)... visit the website www.fabulousacoustics.com and if you are interested to buy, lemme know... i can probably send it from my country...

Another option for you to consider is Scanspeak D29 and Scanspeak Revelator midbass... notes, do not buy the R29 as it is harder to cope up with car environment...

[heimerich]

fyi, Fabulous Acoustic midbass is made by Audio Technology (Skanning)... and unlike any other tweeters on the market, Fabulous Acoustic using Ribbon instead... i assume you know how the ribbon tweeter works... I used to have R29 in my car and I decided to get rid of it and go for Fabulous Acoustic FA1 and i never wanna look back...

If you can afford to buy a C7.4T, then by all means look at the high end model of some of the widely known high end brands (Dynaudio, Seas, Scan Speak, Rainbow, Morel, Focal, etc.). I believe that of all the audio components, speakers are the most subjective when it comes to listening preferences, and they do have sonic differences (what may be excellent sounding to me may be so and so to you).

If I were you, I'd go for Seas Lotus Reference because of its excellent midrange performance, snappy midbass and very smooth highs. And to some people Seas speakers are very close to being transparent; that is, they neither add nor substract anything from the original signal upon playback. With tubes being 2nd (and/or even) harmonic distortion amps, you might as well produce those enjoyable-to-listen-to distortions with accuracy.

Cheers,

Bon

PS: You lucky sod (if you do get a brand new C7.4T), I could only afford a 2nd hand C7......but it's still a C7 nonetheless!!

[mlim3]

I can't seem to get into that website...Are you sure that's the correct website?

Thanx guyz!!!

You might want to look at milbert 235 as well. I use it on bumpy road in Bangkok for 17 years and it is still in working condition. Along the line I have gone through 1 set of tubes due to normal mantainance cost A$250 all up or you can auction vintage tubes from Ebay but that will cost more and definetely sound better. I personally never heard anything better than milbert before not even Luxman, Mcintosh, or alpine F900. so for the $$$ milbert have the longest service life and the best sounding amp I ever own. Their might be something better on the market but I just haven't discover it yet.

[LongGone]

C-7.4T is an amazing piece of gear. Not cheap, but hand built quality rarely is.

[heimerich]

Milbert has one of the best tube amplifiers in the car audio industry... and i think the price is not as expensive as Trutechnology...

Go for the G2si I have use G3 and I feel like killing my self!!!! be very careful about this thing it is so fragile only one pop from an amp is more than enough to burn everything. I would recommenr you to use 4Uf camp as a safeguard against any disaster. While ribbon are very detail it is very hard to get the staging right. riggon is very localise due their narrow off axis response. I personally don't want to waste too much time getting the angle right. it will work great and sound great but you stage will end up having nearly no pan. only hard Right Center and hard Left with virtually nothing in between. But the detail is far better than the Ring radiator. I hope this help

hey golf,
thanks for yer comments.......mmm.i was exactly goin for the G2 as i can get it for a very good price. and yeah the fragile nature of the foil is to be considered i guess..but AC ribbons usually have well conforced casing now...i think unless somone tries to poke it with a stick..i guess its reasonably safe for the car. may i ask wat sort of midbass did u use with it.did u go for a 3 way or 2 way. But if i go ribbons i like to go ative though...makes it easier to tune when on the road whenever i want to.

[golf_bht]

Gp for G2si. Even G2 scale is too big for a car. Whenever the scale is bigger you will need more space for it to do a propper job. no matter what you do, don't connect the ribbon directly to your amp. you will kill it!!!!! my mids are Fostex FE168 E Sigma. the only mid to match the sensitivity of the ribbon without killling the piggy bank. You can go Lowther if you like super hi-end stuff. I ran my ribbon 3 ways. with DLS IR3 softdome mid.

[bodapa]

Speaking about ribbons golf, are you familiar with Swans drivers? What do you think of this? Swans RT1L

Also, have you heard the LCY ribbons, too? Either the 108, 110 or the 130 drivers. Oh, for those who don't know: LCY

Cheers,

Nop I have use only 3 ribbon so far. Infinity Emit, AC G2 andG3. I have read some article about the ribbon you have mention above but Ijust haven't got a chance to audition them. so couldn't help you much. Regguading the material of the ribbon, pure aluminum is the best. Kapton ribbon sound quite dull and a bit harsh to me.

[Reza]

Is it true that u can fix yourself those ribbon tweeter?? I read the tutorial on how to fix it and it seems quite simple, just a aluminium foil and glue lid (to make the zigzag pattern), but then the material would be different right??
