An update on my personal stereo system.

Got the Modi 2 modified some months ago, to the point that I can upgrade it if one wishes. It is indeed world class.

My monoblocks, triode connected, are using Winged C KT-88s with Amperex orange, A frame, PQ 6dj8/Ecc88 made in Holland input/driver tube as reference. (Good luck finding Winged C KT-88s).

As such, I am working with different combinations of currently manufactured tubes to obtain the best quality sound, closest to my reference tubes, with prices people can afford.

This requires that I use two switches so I can find a new manufactured tube combination that "sounds" closest to my reference. The reference was obtain by special proprietary listening tests to make sure the amps do not alter the sonics of the input. (This same procedure was performed with my 10A and perfect 11A line preamplifiers when I was still active. I am retired now.)

Right now I am working with SED KT-88s and JJ 6dj8/Ecc88 tubes. Will report later on findings.

I am hoping this experiment will help others find a tube combo, reasonably priced, that can be made to sound awesome in their components, with some tweaking. Something worth trying that will not break the bank.

Hi Steve,
Interesting you should mention the Modi 2 made by Schiit. A few years back, Jeff from Sonic Craft was quite enthusiastic on a Schiit dac mod, although I cant recall the model. Iím curious as to what was done to yours and the cost.

Thanks for the inquiy. The sound is so open (of course the speakers are totally gone), superlatives galore. I am not even interested in auditioning another expensive dac/player etc.

The mod included disassembly, working with the tiny pc board holes (working in static type conditions), changing, out boarding output capacitors to Mundorf Supremes, poly a portion of the power supply (analog), Vampire all copper jacks, 6n pure copper wire from Jenalabs. Mount, fasten parts. ~2.5 hours labour since I have it down.


I am figuring ~$599.00 plus shipping/handling without the larger chassis. The customer would point me to the part number and I would order their chassis, or other part selection. Of course, I cannot guarantee the sound quality if they wish custom capacitors.

The photo below uses an old 17" x 10" x 3.5" aluminum chassis, used parts so I can test and easily make modifications. No hole drilled for USB cable. I assume one would want a much smaller chassis, although 2 1/2" minimum height chassis would be needed. Width and Length would be dependent upon layout. For example, the output capacitors could be run directly back from the dac, so the length could be half or less.

Cheers

Thanks for that info, Steve. Thatís a very nice price, especially because you think so highly of the sound. I was just on the Schiit website and wasnít aware that they had so many products. I now recall that Jeff at Sonic Craft was so enthused over the modded Bifrost. My Border Patrol SE dac resolves beautifully, but Iíd be quite curious how it compares to your Modi 2.

I would not mind auditioning yours first if that is ok. I want to see just how close they compare in absolute terms.

Actually, I am using the best coupling cap on the planet (cap went extinct some years ago), but the Mundorf Supreme is a real close second. I would also have to rearrange the caps and button mine down before shipping.

Steve,
I just sent you a PM. As Iíve heard of you since Marty DeWulf was writing Bound for Sound many years ago, Iíd very much enjoy your thoughts. Marty raved about your 11A preamp.

Thank you Nick. Sent pm with address. I will take care and will post my thoughts. Yes, both Martin DeWulf and Rich Weiner from Bound for Sound purchased an 11A for each of their reference systems.

The 10A line preamp was one of only three that made the "Exceptional Merit" list of BFS.

Cheers and great week.
