Warmer, wider, higher, sound and soundstage.

Huge size. Hot air flow from the 805 tubes. Atypical face plate from the traditional VTL "grill" faced amps. Sometimes when turned on, shuts down my other electronics with it's emorous pull on the circuit in the House. This and I have the audio circuit isolated from the pole to the wall so as to avoid any loops.

Sometimes I am concerned that the Tri/Pent switches should be hidden in back in case toddler or wife would just flip a switch during operation..

I am refererancing the VTL ST 125 stereo amplifier with 805 tubes. This amp allows one to use toggles on the front face to choose triode or pentode operation.
The manuel says the amp outputs 60 watts Tri and 125 watts Pentode.
I use the amp primarily for music via CD and Phono, I have settled primarily on the lower Triode setting for playback. I do have a home theater set also routed thru the amp and switch it to pentode for movies to approximate the output of my 5 channel amp which operates the center, 2 side surround and 2 rear surround speakers. The amp has operated without any operational problems and the sound is textured, warm, and harmonically involving in a way the Conrad Johnson 2500 and Forte Model 3 prior amps could not touch. The amp also brings back warm memories while playing vinyl in a more human, textured presentation. I use a Sota table, jelco 25 arm and Goldring 1042 (wow) set up thru a ps audio version III pre pre to a Audio Refinement Dsp II in bypass mode (avoiding all digital circuitry) and vinyl has again become my favorite source. The CD playback is via an Audio Refinement Complete CD and Theta Data Basic Transport to the Dsp II Dac, suprisingly different expression for each. The transducers are the Von Schweikert VR 3 towers with upgraded wiring and Mid Ranges.
Well I must say the VTL was the last item added to the chain and this was a watershed improvement even over highly rated SS amps with double the power. Particularlly the life like presentation and warmth of the sound with higher and deeper sound stage has my running around adjusting loudspeaker positions with glee. I am finicky and fussy about the tunes and I am totally immersed and pleased with the VTL ST 125.

I have this amp set up as the Stereo section of my 7.1 setup, It powers the Main LR speakers in my home theatre, and is the Amp for Stereo listening. The Speakers are Von Schweikert Vr 3's the cd is Theta Transport or Audio refinement Player, the Pre and Dac is a Audio Refinement Pre Dsp II. Turntable is Sonographe Sg 2 with jelco arm and Goldring 1042 MM cartridge.

I am totally happy with the amp, I listen to Stereo much more that Movie Tracks and this unit unites well with my towers and vinyl is just intoxicating. The tubes seem to run hot, but they bias well and have consistent sound. I often operate in Triode mode for relaxed low level listening, I do however enjoy the switch over to Pentode operation as well. Smooth, well articulated mids, fine and deep soundstage, elegant but not sharp treble extention and proper bass, will detail not slam.

Conrad Johnson, AR,

Keeps the circuit simple and uses sonically pleasing EL34''s which not only gives that great tube mid-range, but is a smooth treble tube. As for bass, it''s surprisingly authoritative and warm without being overdone and out of control.

These two monoblocs will heat up a small room noticeably. They are heavy to move which I myself find a strength due to being well built, but may be taxing for some folks and shelves too.

My review will be for a pair of Deluxe 100 Monoblocs by VTL. I think that, in cost and build, this amp is the a close relative of the stereo 125. These amps just sound like someone who loves music built them. The mids are enough to dive into with great dimension and a kind of lucid clarity that even high end solid state strives to match. The highs are smoother and still "all there" than the usual solid state. Less irritating if you will, highs that invite you to study them and not just acknowledge that they are in fact present. Mids and highs, where the bulk of the information in music lies, are presented in a very intoxicating way with this amp. That would be enough for me... There''s more though, I am getting good bass too! I really did not expect it to be so full and real. Perhaps it is the combination of the EL34 tubes and the way David Manley has his transformers manufactured. Whatever it is this amp is a stone classic. No wonder Chad Kassem''s audiophile reissue and blues artist recording studio (Blue Heaven) uses this amp. I''ll bet his is tweaked to the nth degree, mine isn''t and it''s so rightous that the only thing I could ever wish for is a larger version of it. Yes Virginia, I know there are three or four bigger versions, but I did not say I wanted to pay for a larger one, I just said I wanted one. Make it two since they''re monoblocs and right now is a good time if wanting and dreaming is the deciding factor. Bravo David Manley! Tubes are now getting a much higher profile and your mid eighties starts were visionary, you were ahead of the curve. I wish you would come back because at least you tried to make the entry prices as low as possible. If my amps are evidence of the quality of the goods, you had a good handle on the needed quality/price ratio. My advice is to buy a set of these if you can find them in good condition. By the time you''ve re-tubed you may not think you have an end-all bargain, but the current tube amps are so pricey it is a great way to get a fair price which is what I did myself and I am very very happy. I''ll say it again, this amp is a stone classic.

Really none, my first tube adventure!

I recently went through a year long ordeal with a pair of VTL 300 Monblocks, they remind me of the old Triumph TR6, they ran great over the weekend but were in the shop the remainder of the week. Reliability is awful with the VTL's and product support is nonexistant.

Ignore the 2 moronic reviews below:This is NOT a review for 300w monoblocks, and VTL is not a British company-Made in California,USA. VTL is excellent product for the money

Was struck by the VTL review I read above. It is exactly my experience. I had a pair of VTL MB-300 Deluxe monoblocks and was very disappointed in their quality and, especially in the attitude and lack of support from VTL. Perhaps VTL is too busy being famous from their recent "best of show" award to care about the end users. Typical British attitude. No wonder we kicked them out of the U.S. over 200 years ago. Whatever it is, I will never own anything else by VTL and believe that the sound and quality I get from my McIntosh MC300 is "as good as it gets". So good that I will be adding a new preamp and speakers over the next few months. Would give the VTL's no stars, if that rating were available.

Here is a tube amp that possesses a glorious midrange while having bass slam and sweet highs. Tetrode (128 watts per channel)/Triode (50 watts per channel) it has the ability to drive many different speakers. It is rarely seen on the used market (for good reason). Worth seeking.

Musicality

ignore rumours of unreliability, mostly this is due to poor tubes which die prematurely.

4 years on same set of tubes, no failures, only beautifully presented music. These amps are a bargain. Mine was bought second hand and so I put in a decent set of tubes as I had no idea how much use (or abuse)the old ones had been given.
Daily use, all types of music, great sound so long as speakers are not too hard to drive.
