Thumbs up small tanks!

Hello guys! I have some pictures of my new integrated amp from Aussie amplifiers,the HPA-nxv 200. I am still waiting for the input caps (sonicap 3.9uf).These kits are wonderful and the service from Anthony is top notch.These amps are really top quality all over and the sound is fantastic!!! I had it playing for a couple hours at really loud volume and the heat sink got just warm. I strongly recommend these kits.Thank you Anthony for great products and excellent service.

Hi!

This is my take on Anthony's HPA-nxv200 amps.

Well, two things to mention:
- I did not use any input coupling caps, because my dac already has output coupling caps.
- As you can see from the transformer and the heatsinks, this is kind of a low power version. I use a transformer with 2x24V secondaries which gives around +/-34V rail voltage (around 50W per channel at 8 ohms).

Do you like the sound?. I really like it, I have pushed it really hard and the sound is fantastic, I am using a 670vac 35x2 that gives me 48vdc per rail and I am using 20000uf per rail, I also noticed that the heat sink got just warm after having it playing loud for four hours, I am using it as integrated amp (using 10k potentiometer). The service from Anthony is wonderful.so far my tops amps and services are from Audiosector(Peter Daniel LM3875) and now Anthony (Aussie amplifiers HPA-nxv200). These are my two top. Right now I have the HPA-nxv200 playing in my living room and it will be there for a long time!.

By the way, your amp looks really neat,clean and professional made.

Hi lanchile!

I already noticed your HUGE tranformer! Nice one ;-)
Btw, I spoke to Anthony before I build mine and he told me that a higher supply rail voltage doesn't give better sonic results, that's why I build mine around this rather small 250VA transformer (Thel Audio) with a total of 40.000uF smoothing capacitance (Panasonic TS-HA). For my speakers the power is more than enough (simple 2-way, 90db sensitivity).

Well, yes, I do like the sound! I also build a LM3875 amp before, and I must say I seem to like the sound of discrete transistors better than the chip sound. Discrete designs to me simply do sound more, well, "real", if you know what I mean.
The nxv200 are really very well made amp modules, and Anthony did an excellent job here. Very well build, very reliable and stable.

I would say I find the sound to be just a tad more on the bright side than on the dark side of neutral. But this is a matter of personal preferences and system synergy. Perhaps I have do to some more work on my dac and/or my speakers...
(Or perhaps I listened far too long to a Naim power amp... ;-)

Or, here is another idea: This was the first time I used those Panasonic TS-HA caps in a power amp ps. Now I wonder if some BC Series 051/056 would have been a better choice?

But I think everything else about the nxv200 amps is top notch!

Regards!
Martin
