There was a problem getting IC buffers, TI BUF634 SOIC, for this amp a time back. I still don't have the money to do up a little diamond buffer prototype for this rig yet (seeing as there is a Ducati in my budget...) and IMO the national semi buffers discussed in this thread use slightly more current than I desire in a portable amplifier. I prefer the sound of the National chips over the more mellow BB sound but I'd much like this amp to pull ~30 mA (less being better). However, I just got a notice from mouser on friday that the buffers (TI BUF634 SOIC) that I backordered in june had finally shipped. Oddly enough, I was just about to check this thread out one more time before I ordered the rest of the amp components from mouser today.

I think you will be seeing more reports on this amp as the buf634 chip becomes more readily available.

I built two. One paired with an Alien DAC for a friend and another as a straight amp for myself.

The only issue was operator error installing one buffer upside down.

Since I couldn't find any Buf634's at the time, I used LMH6321 instead and they bouth sound great.

Great, I'll look forward to hearing more about it.
