The Lampis got them, the Yggys are getting them; in fact a lot of great designs yield a smoother, more detailed sound with mods. Apart from SW updates maybe there are parts up to some tweaking. Most obvious and super easy to implement are things like upgrading the power cord, shorting unused input…

[image] tedsmith: I’ll lower THD by refining the sigma delta modulator. When I was tuning the new SDM I was fighting the noisy attenuators (which we’ve removed from the design.) I had to make some compromises in THD to lower the attenuator’s noise contribution. Without them I can readjust the SD…

Will listen on a drive this evening…Ted looks younger than before…some noise removed probably.

You might want to wait for the new nickel transformers. The VOCM mod parts and transformers are listed in detail in this post topic.

Hard to find in this thread, and my budget is so low, I’m not 100% sure I can afford your unreleased awesomeness.
