Bottom Line:   
This is for the original TT25, not the re-issue.

The 1st thing came to mind is they are really tiny. The tube cage is so small that some of my Telefunken EL84 won't fit correctly. But even more so, I *have* to remove the cage because the units overheat very quickly. You don't want to put them anywhere near your speakers or the veneer may look funny.

Sound-wise they are super steal at $650 (or $1000 for that matter, for an EL84 tube based amp). Be forearned that 25wpc is rather over-rated. When driving the Coincident Partial Eclipse (93db) the amps sound like 15wpc as it distorts very quickly as I cranked the VTL 2.5 preamp to 12'oclock position.

If you do have an fairly small room (well, if your budget dictates you to pick at this price range, you *do* have an small room!) and efficient speakers (I'd say 93db minimum), this should be on your very short list.

Of course, I dumped this pair because I heard many stories about the TT25 overheated and died. Otherwise, it woudl have been an 5 star all the way.

P.S. I owned numerous EL84 amps before, and once auditioned for hours on that Manley Stink-Gay thing (joke) that cost so much, this TT25 sounds the sweetest.

I purchased a pair of the older red-sided VTL TT25's in 1990 and have been happily listening since.
I had some trouble with a humming power transformer about 5 years ago and got new power trannies for both amps which noticeably improved the bass.
Although cute the tiny box combined with the Manley "verge of Chernobyl" operating spec can cause overheating problems. Smaller caps on the circuit board with high temp tolerant types to good effect and would replace the elecrolytic power cap if I could find something from Elna to fit the hole in the casing. (All this of course would void any warranty).

I use JJ EL84 output tubes and prefer their dynamics to the Sovtek types (only others tried). The line stage is a Raytheon Triple Mica Blackplate 12AT7WA and the phase splitter a Sylvania Gold Pin 5965. I have tried Amperex Bugle Boy, Brimar CV455 and JJ and Sovtek current production and find the above combo appreciably better than the others.

The amps are driving DCM QED1A's (old, eh ?). They do have bass but an active semi-conducter sub-woofer would relieve them for what they do best - mids and upper - if you must have the pedal notes get a sub.

This is a review for Limied Ed. version. This little tiny triode is too damn wonderful for 'toys'. replacing the big brother VTL 300B monoblock is not disapointed. they doing a great job driving JMlabs Micro Utopias and Merlin TSM Millenium. you better hurry to get this tiny monoblocks because it only made limited 500 pair. much more better than the old version, you'll be surprise.......

I have never been motivated to take the time and write a review, but these TT-25's deserve the praise they have received here! I would agree with pretty much what has been said so far above and add that the most amazing difference I noted was the tremedous ability of these amps to sort out the proper dynamics for various instraments being played. Previously I have been using a McCormack DNA amp and I thouht I really had the deal closed on amps, but in comparison with these Tiny Triodes, even the McCormack almost flattens out the dynamics. The imaging is still superb with the DNA (though no better than the TT-25's) but there is simply more life in the TT-25's. Not even a close call here. They have made a tube convert out of me. I am running these amps with a McCormack SST-1 transport, and the Creek OBH-14 24/bit D/A with passive preamp stage built in. This is run directly into the TT-25's for a very simple and direct path. I am using Audio Physic speakers.

I recently purchased some JmLab Mini Utopia loudspeakers and I went
searching for an amplifier that would make them sound smooth. I love
the speakers but they can be bright with some electronics. Well I tried
Bryston amps and preamps, the Proceed HPA 2 with the Bryston preamp,
a cheap Cambridge Audio integrated, Antique Sound lab (tube) integrated,
and the VTL IT-85.

Out of these the VTL really smoothed things out. The big
250W Proceed was really heavy on the bottom and this greatly detracted
from the midbass/midrange. The the Bryston was also bright. Now,
the Antique Sound lab was the worst. It just screached on top. Shrill.
It was also really loose on the bottom. It looked to be of very good
overall construction and may perform better with better output tubes.

Anyway, the last thing I brought home was the tiny triodes. They were
much better than all the solid state amps and sounded comparable
to the VTL IT-85. The 85 seemed to have more power (it does) but
it just sounded flat compared to the tt-25s. I tried both the VTl 2.5 and
5.5 preamps. Initially, I decided that the 5.5 was more open and real.
But after blind tests, neither me nor my wife could tell them apart.

The bottom line is that the qualtiy of sound I get from the tt-25 is top
notch. Also, they NEVER sound underpowered with my ~90 db
efficient speakers.

A side note. They sound a little smoother in triode and they provide
plenty of punch with my speakers so that's the mode I like best.

I am thinking about tube rolling ( mullard EL84) the output tubes.
If anyone has tried this I would love to here from you
