Here's an interesting new pro headphone amplifier, hand made in Serbia:

It has very good specs !!!

For the amplifier gurus here, a question: how does it compare with the beta22?

If no one has heard it, how the FUCK would we know how to compare it to a Beta Deuce Deuce?

It looks very well made, though.

Ok, two very good points made so far ... :)

The beta22 is fully discrete and has a much higher power output, much better PSU, etc. Although for a pro unit this doesn't look like a bad little amp, architecturally it isn't in the same ballpark with a beta22. Good specs are pretty easy to achieve with opamps running with negative feedback. I agree with the balanced in/SE out comment as well. I can't tell, but is this really fully balanced or does it just convert bal->SE?

The question I have is are all those TO-220 devices regulators? Sure looks like it. That means this is basically a chip amp...

I'm with Marc, this is a basic chip amp from the looks of it so the competition is something like the RSA HR-2 or Rudistor, not B22. Interesting volume control though, possibly some vintage USSR stuff?

The TO-220 on the left is a regulator, you can see from the side shot. From the top shot you can see they are all National devices, hence my deduction. The soic devices are probably relay drivers, that would be my guess at least. It could be a double sided PCB I suppose.

It's 1400 euro ... that's why I wanted a comparison with the beta22. :)

€1400 would buy you a set of Quad electrostatics in fine repair, nevermind that little box of bolts.

chip amp for sure. Notice that the power input is AC. Therefore the

things on the heatsinks have to be regulator chips, 2 for each channel.

5th one is likely a 5 volt regulator to control the switching.

I'm waiting for the buckets to throw ping pong balls in.....

At the very least you saw another amplifier ... I have no relation to the manufacturer. :) I thought it was like 400-500 euro, like the lake people amps, later I found it's so expensive and I was wondering why ...

PS: There's a dismissive attitude towards head-fi here ... I don't see why, you lot are just as bad and stuck up to boot. Get off your high horses, your shit smells the same as everybody's. Serious people and excluded. :)

Could it be due to the smiley at the end of the attack? I mean how could you possibly even think of banning eugenius after all that he's contributed to HC?

why do i have a sudden desire to hit that red button?

But you didn't do it? A bit uncharacteristic... :)

Most of us have been on HF for a long time so there is good reason for our attitude. To us you are just like all those noobs on HF which look at the price of a component and think that has any bearing on its performance. To quote Oscar Wilde, "A man who knows the price of everything and the value of nothing". A version of this should be the HF motto...

There're the other kind of noobs who believe they found giant killers everywhere, and praise nonsensically pieces of shitty sounding gear. For instance Little Dot gear :palm: which is crap even considering its low prices. There are several dozens of such gear being praised ad nauseam there.

Seems like it's probably time for you to take it on down the road, then. Take care now...

If that's what it takes to ban a user ... I don't know how you stand such people like "sandwitch around my kidney - crapping monkey" Voltron or "what do you eat - FUCK" JBLoudg20. :)

How the hell did I get roped into this?
