T+A elektroakustik HV Series Components


T+A stands for Theory and Application.

I'm keeping this broad and open to T+A's HV Series components (HV = High Voltage),

Which (currently) includes two integrated amplifiers, two multi-source players, preamplifier, amplifier, power supply, and SACD/CDP/DAC.

Creating this thread for owners to share their impressions, findings, thoughts, experiences, and questions about their HV components. Comparisons to other T+A Series products are also welcome.

Joe Casey the Dagastino Mommentium is in our opinion a good sounding product but way over in flated for the sound quality it delivers.

When we were shopping for a reference electronics line we considered Dag gear but when we looked at the prices were turned off, it does appear you are paying alot for that look and the craftsmenship.

Compare a Dag s250 which costs $35k  for a 250 watt stereo ampfor the same money you can get a T+A P3000HV a 300 watt stereo amplifier with a 1,000kv transfomer and their upgraded power supply which add a 1.2kv transfomer which powers the output stage and the internal transformer powers the input stage of the amplifier so you have a two chassis reference amplifier for $3k less with more power and a suprior topology and if you want to start you can just purchase the P3000 HV amplifier for $19k this is a 300 watt stereo amplifier which can also be bridged into a 480 watt monoblock.

So even without the upgraded power supply you are $19k for a very musical very powerful stereo amp made with extraordinary parts quality, design and technoloy vs $35k for the Dag. 

Compare the Mommentum integrated at $45k to the T+A P3100HV a $23k T+A unit, the T+A gives you an option for a built in phono card, room eq functions and 300 watts of power also with an option to add the outboard power supply, and you are still paying $22k less!

David_Ten, can you please describe the sound of the P3100HV in compare with Pass. Is that characterized as fast and dynamic, natural, organic, how about its transparency, top end, bottom end, midrange? Please share more details. Also, did you have the chance to compare 3100HV with other top integrated like Gryphon, Vitus?

Thank you.

Please share more details. Also, did you have the chance to compare 3100HV with other top integrated like Gryphon, Vitus?

Or Absolare, Ypsilon, and AudioNet.   I would love to hear the AudioNet Watt.
@denon1  @russellrcncom   In addition to the Pass XP20 - XA30.8 pre and amp combo, my T+A PA 3100 HV was compared, in home and over time, with these integrateds: the Lyric Audio Ti140 MkII; MastersounD Evo 845 (briefly, but in home); and the Ypsilon Phaethon; prior to my making a final choice.

I stopped additional comparisons because I was more than satisfied with the T+A. And, to be honest, though comparisons can be fun and exciting, they take energy and time to coordinate, setup, break in, and evaluate; not to mention taking away from the pursuit of purely enjoying the music.

I also needed to get busy optimizing my system with the T+A as a key component in it.

Recently, I've been running comparisons between the T+A and my  Grandinote Genesi Preamp and Scott Sheaffer's Found Music 2A3 mono amps.

All in all, I have compared the T+A PA 3100 HV with a solid state pre-amp combo (Pass), two tubed integrateds (Lyric, MastersounD), a hybrid tube-solid state integrated (Ypsilon), and a solid state pre with a low watt SET amp (Grandinote + Found Music).

I found all of the amplification chains highly satisfying and I can easily recommend each one, though with caveats for each.

This doesn't need saying, but one's preferences, goals, room, and system synergies will play a far greater role in choosing one over the other vs. simply the component on it's own merits.
@denon1 The T+A PA 3100 HV has better control, has better resolving power (more insightful and nuanced), is more transparent, is more impactful and dynamic, is more natural in it’s warmth (surprising outcome here), has the edge in timing, presents voice (male and female) with greater realism, etc. etc.

A negative for me, was that in direct comparison, the Pass gear sounded grainy [in direct comparison only] and didn’t offer the level of insight, richness of texture and harmonics and musical density that the T+A does [in my system, per my preferences].

I clearly and easily preferred the T+A over the Pass duo and found it to be superior.

However, once I added the SR PowerCell 12 SE with the Galileo HC PC to my system, the Pass combo sounded fantastic. Had I added the SR power conditioner first, I would have been less driven to look for alternatives to the Pass combo. BUT the T+A also moved forward with the PowerCell 12 SE in system. Closer now, but I still prefer the T+A and continue to find it to be ahead of the Pass combo.

Reiterating: This is based on my system and my preferences and goals.

Please Note: I can see why another member would be very satisfied and happy with the Pass gear.

And I still own my Pass combo.
