No clue. I haven't tried or looked into it. Would be nice though.

I threw in additional upgrades to my DIY integrated amplifier:

Overhead shot of the preamplifier section and two power amplifier boards. I added 2x Elna Cerafine 470uF/25V power capacitors to the post-regulation power supply of the preamp. I threw the LM4562NA in the preamp into deep class-A operation (3.9mA/channel).

Close up of said modified preamplifier section. The sound changed pretty significantly (for the better) with the addition of the 1N5312 CRDs to throw the opamp into class-A operation.

Complete general shot.

I used a 530VA Avel-Lindberg toroidal transformer.

Very cool. What are the specs and how does it sounded compared to your SRM-1?

SOHA w/ jisbos buffers- Sounds much better than my pimeta- I'm very impressed by Steinchen's buffers

glad to hear you like them

but in fact they are AMB's buffers, I just did the prototyping and evaluation

I implemented additional upgrades to the power supply section of the preamplifier section in my DIY integrated amp:
DSCF6244.jpg

I added numerous capacitors ranging from 0.1uF to 1000uF to the post-regulator power rail (two TREADs create a +/-10.77V DC power supply) and added 2x 3.32K bleeder resistors.

These are the remaining capacitors in the power supply of the preamplifier section. I had extra bipolar 4.7uF/50V BlackGates lying around, so I stuck those in next to the 470uF Cerafines and the 150uF Panasonic FMs.

My setup, nothing fancy here. CMoy amp with a TLE power section. Enclosure is a $1.00 wood box from Michael's. Much better than the old plastic box from Radioshack. (Sorry about pic quality, I am completely battery-less so I had to use my iSight)

Haven't had anything to post here in quite some time. A very belated christmas gift:

It's an optimized Cavalli Jones with variable feedback. I'd put it at 80% done; still needs the bottom plate painted, feet and the knobs bored out. Drives my SR225s better than anything I've heard.

thanks, bearmann.
yes, the case is all wood. i stumbled upon it in a local stationery store. when i saw it, i grabbed a ruler from another aisle, measured it's dimensions, and found it was the perfect size to house the board and all the connectors.
