Amp for Vintage Heresy

Great feedback!

no I don’t believe they have been updated but they were sold to the owner I purchased them off of from The Turntable Shop in North Van that used to specialize in vintage audio so he might have worked on them.

I will explore restoring the Hereseys after I spend more time with them.

Pass is solid state.

With that said, if you go solid state, the Coda S5.5 will be your best bet. Long thread elsewhere on this forum which I've linked. Many happy users including myself.

I've had decades of experience with low powered tube amplification. Lots of good suggestions above. I would say your best current bet, especially if you don't mind a pretty simple build, would be the Elekit TU-8900, also linked below.

Finally, as also suggested above, your biggest bang for the buck would be upgrading your crossovers. A suggestion is linked below.

Oh yeah, forgot to mention as also recommended above, if you go push pull tube, IMHO, EL84s have always been my favorite given a sufficiently efficient speaker like yours.

For example, the Manley Stingray would be killer with your speakers. You can usually find a nicely priced one on the used equipment sites.

Speaking of push-pull EL84s, a musician friend recently heard the little Black Ice FX10 at the Tampa audio show and said it "rocked."  Might be a good fit here.
