T+a pa3100hv

I was told the HV3000 plays up to 30W in class A, when I auditioned it a couple years back.

As far as I know, the power sections in the HV3000/ HV3100 are pretty much the same. Most of the work and changes in the HV3100 went into the pre section and power management, it says on T+A webpages.

I have both in the store. The Diablo 300 has that big HUGE soundstage, tremendous bass and seamlessly limitless power on tap. The PA3100HV is breathtakingly beautiful in design, it has a very “tube like” sound. Buttery smooth on top.

They are, to me, the two best solid state integrated’s I’ve ever had. Just fabulous. Really, both are in a league on their own.

Which one do you prefer on vocal tracks ? Thank you.
 
Just out of curiosity, I emailed T+A about class A power of the PA3100HV. They responded very quickly stating the amp is up to 30 watts in class A. They mentioned heat would be an issue if it was more....
 
I have been listening to it for a while now and the needles have rarely even moved [emoji3].

I wonder who's buying the auxiliary power units???

Think of it as adding a really good power cord and power filter to your setup.

I have heard it with the power amp and the integrated. Definitely makes sense for either one.

I have been listening to the little T+A AMP 8 the past couple days (giving the SET amplifier a little break). What a wonderful sounding amplifier. Separation and sound stage is fantastic. I would say a little more accurate and resolving then my SET amps, but maybe not quit the warmth. It definitely draws you in.

And then I read on T+A website:
"The overall circuit design of the AMP 8 is that of our sensational PA 3000 HV integrated amplifier, which is why the input stage and the voltage amplifier stage operate at much higher voltage potentials (HV – High Voltage concept). The input stage is a cross-coupled J-FET cascode amplifier, while the voltage amplifier stage is a single-ended Class-A Hawksford FET cascode. The output stage is responsible for current amplification, and is equipped with ThermalTrak TM high-performance audio transistors to ensure that the bias point is totally stable and free of inertia effects."

Now it makes sense. It is using the same designed amplifier that is in their integrated amps. And I think, AWESOME! Bottom line, is it sounds fantastic! From what I understand (again from T+A website) the PA 3000 HV and the PA 3100 HV use the same amplifier section. The differences are in adding the meters and I believe a redesign on the pre-amplifier section.

Kouppis, Should you need power cords, contact me. My Furutech cords have opened the amp up nicely. It seems more dynamic also...

Thank you, that is very kind. However, for me the T+A 3100 HV is so far only a visitor to my system, as I wanted to test it a familiar environment.

The little T+A AMP 8 does not get the respect it deserves. Outstanding amp for the money. I know it very well. I've even successfully run ATC SCM19 and SCM40 with it. These are not the type of speakers someone would expect to drive with this amp, but it did a shockingly good job.

Kuoppis, Firstly, sorry about misspelling your "name" previously. What are your thoughts on the amp? I'm very anxious to hear a comparison to Soulution, which is the ONLY gear I would even consider swapping my T+A gear for... Thanks!!

No worries about the moniker [emoji3].

In my view the T+A 3100 HV is a really great amp. Great detail and resolution, good bass, smooth mids and highs, exemplary build quality. Tremendous value for the money really. But the Soulution 511 outclasses it in every possible aspect, which is no surprise as only the power amp is double as dear. I’ll write more about the Soulution and refer more to the differences I hear, as soon as I get the corresponding pre into my system. But I could easily live with T+A as well.

Hi,

‘’I am looking to purchase a used PA 3000 HV. I realize it’s the previous HV Integrated, but the price is tempting. There is now way I can afford the newer 3100 HV.

Question is if there is any huge difference between the two? I don’t care much about the fake VUE meters

T+A has made it very clear: any PA3000’s still floating around out there will NOT be offered warranty, despite claims by terminated dealers to the contrary.

As for the difference, a little sonically, but the big difference is the ability to add the PS3000HV down the road. All the ones I’ve sold, the customers rave about this add on power supply.

I’ve had both the HV3000 and HV3100 in my system for some time. IMHO the HV3000 has a slightly more transparent top-end, while the HV3100 offers a slightly more pronounced bass.

Hi guys, i will try to make a shootout with the T+A int, the CH Precision I1, Dart-8550 mkll and Technical Brain int on Borresen speakers.

Interesting comparison, let us know what you find out.

I recently tried to find out what has changed from CTH 8550 to the mkII version, but did not discover much info on that. Except it has sightly less nominal power due to the new amp topology (as introduced in the 468 monos).

Also, I auditioned the mkI years ago for the Magico S1 mkI’s. While being a very nice sounding amp for the WA Sophia III, it did not have sufficient punch for the Magicos.

The PA 3100 HV can drive the Borresens without doubt.

Never tried the CH Precision or Technical Brain.
