I have full intentions on bringing back a new, enhanced version of the Purity Audio Design Reference preamp circuit. The Reference has long been our most popular and well received/reviewed preamp. This will fall into our upper level products.
We have a scaled down version that is available in the Spirito/Harmonia Jr chassis for those who want a top line 6SN7 linestage without bells and whistles. Just pure sonic heaven.
In fact, was just listening to the last custom unit last night! This is a full Reference with 5U4 power supply driving our MB2A3-SE amplifier.

We have multiple Harmonia Jr chassis in stock ready for your custom build.

That's great, Bill. Pls provide pics when that 2026 chassis is done.

Thanks, Bill . Very nice looking chassis on your preamp. A good idea regarding a universal/multi use chassis.
