You may want to check the lists here and here

I just switched over to the OPA2107 from the OPA2227 and am finding the sound quite nice out of my Pimeta.

The BUF634's have been on backorder with most suppliers for several months. In July, Digikey seemed to have the stock coming in that just came and went, Mouser is listing next April as the next available stock (they used to be listing it as February. It just seems to be that TI is not meeting demand on this chip.

There are a few different ways to deal with it if you want to go discrete.

I took some photos of my pile-o-DIY last night......

The wide case at the bottom is my Buffalo DAC. It gets coax from a Cambridge Audio 540Dv2, and optical from my Xbox 360.

The left and right cases at the top are my S11 power supply and MMM headphone amp. The MMM receives unbalanced output from the Buffalo.

The middle case at the top is my Millett Hybrid Max. It is fed from the Rec-Mon of my 540Av2 speaker amplifier.

Blue Resistors

What are the blue resistors (with the number code - not the color code? The smaller ones?) The look interesting.

thanks

The casework for my proto Bijou has come to an end, about 10 months after the amp was playing music for the first time.

Farrari, that is one hell of an impressive amp. Don't supposed you'd mind giving us a rough run of costs would you? And some internal shots maybe?

Thanks for the kind words gents!

J.D.N, I haven’t keep track of the cost, but it’s probably in north region of US$1000.
Since this amp was built with a personal touch, the cost is a bit higher than all the (more or less standard) Bijou amps you often see around here. BTW, I have added a couple of internal pics here.

Great work!
Looks like a well made and solid amplifier.

Those film caps had to have been a few hundred....plus those nice transformer and those other large caps. I can see where that number came from!

Ferrari, your builds are actually nicer than quite a few professional outfits. A little glitzy, but extremely well done inside and out.

Wow - ever think of building a SSMH? It would be interesting to see your take on it.

About bloody time, you lazy ****. ( and yes I am allowed to say this as the proto in my closet is finally finding a home too - not a Dutch palace, more of a homey cottage ) ..dB

Yeah, nice one Ferrari, nobody is ever going to build a Bijou after that...... everyone now knows they will only hit disappointment when compared to your efforts!

Ferrari, always enjoy seeing your work. This my be my favorite amp build of yours since coming to Head-Fi. Looks fantastic.

A different style of case this time perhaps?

LOL, I was just hoping for the opposite to be happen… the same way it was happened to me a couple of years ago, before I joined Head-Fi in 2006.

At that time, I didn’t know any thing about this DIY-legend, but his marvelous Dynahi has inspired me to try some DIY headphone amps. Of course, not to build a Dynahi and to copy his build, but to do something I truly belief in, to create good sounding and looking amps to listen to music the way I want to… just enjoying music at its best (or as good as it can get).

It’s a great honor to know that some people like my style, however I really hope that it will not influence anyone in a negative way!
