I can say I have the CFA2 (single ended only) and the dynalo mini (pretty much a DIY GS-X ) and prefered the CFA2 for HD650. I haven't tried other headphones but based on reports many people prefer it over the Dyna series of amplifiers.

The 200w figure is most probablt in class B. I have an amp with 100W output @8ohm and the first 25w are class A. Simple to do.

Wasn't an official announcement taking place at RMAF? Any news regarding the new product?

It is actually a good thing that you run your preamp close to maximum volume. This means that you only have as much gain as necessary in your system and don't need to throw it away. It doesn't make much sense to have a lot of gain if not needed, makes for a simples chain of amplification and...

Vidar is a current feedback design, and most amps on the market are voltage feedback design. Search what those terms mean on the web and you'll find good definitions. Vidar also uses a microprocessor to monitor all the working parameters of the amplifier circuit and this way doesn't need a...

There are 4 different power supplies in the Vidar as far as I can tell. 2 unregulated supplies (one for each of the output channels of the amplifier), 1 for the input and driver stages of the amplifier and one for the microprocessor that run the whole thing. So lets break them down but first...

Jason congratulations on releasing the Vidar. Looking at the internal pictures the payout is very well thought of and makes for a very compact build. One thing I saw missing from the specs and could be important for those wanting to leave them on all the time is the power consumption when...

Let me change topic here for a bit, I'm sure someone may have asked the same thing but I won't be reading 2800 pages... When can we expect a higher grade phono amplifier? There are various DACs and amps now and I'm sure you guys can come up with a higher perfermance phono stage? Maybe a tube or...

Hello,   I will look around in my hard drives to try to find the images, if I do I'll upload them! No promises though, lost a lot of stuff a couple of years ago.

You should really just read around, the extra knowledge you'll gain will prove very useful!

This looks like a nice little regulator! It's small enough to be built inside a large wallwart with a trafo for small power applications, should be perfect for a Y2 or small desktop amp. Should be looking for a few of these boards when available. A kit from beezar or glassjaraudio would be a...

 Both the M3 and CKK are available as kits too from Jeff Rossel, at www.glassjaraudio.com.    Then you have the Dynalo, Dynahi, KGSS, PPA, PIMETA V2.    Don't forget the new a20 from AMB as well!

Hello Guys, I'll be the next person receiving the HE 6 from Guilherme. I'll chime in later when I get them! :)   Feedback in my sig!

What about taking some time to read through the dozens of threads regarding 1st time B22 builds and all the other ones? Most questions are answered and you'll find the iformation much faster than waiting for replies here.   There's a thread here which compiles all the B22 threads together...

That is certainly not appropriate. Even though you should always leave feedback either buying or selling, and do so swiftly, it is no reason for the buyer to leave you a negative feedback. You should wait for a response from the mod team.  I believe that feedback posts should not be...
