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…

All of the beta units that went out the door to customers had the attenuator switches removed. There were some earlier units inside PS Audio (and here) that had the functional attenuators, but paying customers never got the attenuators. If you heard an engineering prototype it might have had the n…

Watched this last night: [image] Directstream Mk 2 observations DACs I thought those that are watching this thread might enjoy a long conversation with designer Ted Smith. Ted and I just finished up a 45 minute video chat about the differences between MK1 and MK2. …

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

If somebody has part ordering details for VOCM and Lindahl’s, I sure would appreciate it. I have Edcor4400 and an FARAD external LPS, but am thinking of more affordable changes instead of mkii atm. Inbox me if you don’t want to reveal sources.

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.
