Return to K&K Audio / Lundahl Transformers

Here we go. These two systems are always in flux. All the custom stuff uses Lundahl transformers which I think sound the best. I have experience with others but I come back to Lundahl repeatedly. The dacs and my heaphone amp both use Lundahl transformers. I can't wait to upgrade my K&K Audio phono stage to the hotrod version. Once again, for a price like $75.00, you can't beat the quality. The new dac has been so much fun to use. I still use last years dac which I think sounds very good but the RAKK is clearly better. There is remarkably more resolution and focus. I have been experimenting with power conditioning for a couple of years and am still unsure about what each component does to the sound. I'll let you know in the future. The balanced power transformers and the differential filters are Jon Risch designs. They work in my system, especially on the front end. I feel as though you have to try these sorts of things instead of just talking about it. The big chokes(Richard Gray style) are brand new.Main System:
Sony DVP-S7000
Toshiba SD-2109
RAKK dac passive output

Way cool! All you need to do now is replace the Sonic Frontiers Power 2 with one of Kevin's KT88/6550 push pull designs or push pull/push pull parallel 300B designs.You'll be really cookin then! Nice to get your impression on the RAKK dac, mine is arriving tomorrow. I will let you all know as soon as I have designed a custom chassis for it...
Thanks for the thumbs up, AnandR. I'm headed down the path of a 6SN7 driving two 2A3's push/pull into four KT88/6550/EL34s, push/pull. I have the Lundahl LL1679 P-P transformers from a friend who replaced them with the new amorphous core LL1679. It's big project but I'll be able to build them with Kevin's help. Good luck with your RAKK, you will enjoy it. The break-in does not take too long and is very graceful. I just turned the tubes off for the night after a couple hours of listening. WOW! the tone, harmonics, sense of space and wholeness are just premium. Have fun.
