Hi this is what I turned completely I have connected this with my integrated amplifier after that how it sound is unbelievable seperation was very clear very good bass detailing never heard before.So I have planned to build power amp.Just tried as a test but it turned worth $$$.I think sachin you better know how DIY matters

Jean Hiraga 30W I am gathering parts now

@hifiramr: in case you haven't done it, please try the spirovious resistor mod mentioned her: http://www.hifivision.com/diy/21036-pass-b1-161.html#post591306

R104 and R204 has to be made 306 Ohms (instead of the 1000 Ohms).

It does improve the sound of the B1 substantially.

He just saw the post ..
Very very happy that the unused kit was useful to you. I think it was "destinated" for you and I was just the carrier ...
we must be thankful to Sachin and OP - for Transformer.

You did justice bro - now enjoy and we will be having a lot of" happy dealings" in future..

Already have Sonus Faber concertino bookshelf.

Sonus speakers have very low sensitivity. Yours have a sensitivity of 86 dB and I doubt the Jean Hiraga would be able to drive them to be loud enough.

Yes it will drive very easily its 8 Ohm but not too hard to drive like dynaudio.I have tested it with cyrus and other 50w amplifiers it working fine.If we use class A that should be very much fine thats I am sure

Why do you think this? Do you consider a sensitivity of 86dB to be low? According to me these should be able to get some serious SPL out with that amplifier.

Yes correct usually what I found is I have used dynaudio excite x12 which is 86db at 4 Ohm very difficult to drive that is correct but sonus is 86db into 8 ohm is very easy to drive than dynaudio.Also when I have a class A then that should mach very well.

According to my observation the current flow through the amp will decide its power not the watts.
