Amp for Vintage Heresy

Long experience with these. In college those Heresy’s really sang (and rocked!) with a Heathkit AA-151 EL84 tube integrated.  In today’s market, a Luxman SQ-N150 integrated would be ideal. EL84 tubes are comparatively cheap by power tube standards and with a relatively low heat output. Really lots of EL84 tube amps are out there as they were extremely common throughout the 60’s. 

Pass Xa25, First Watt, Aegir, Dennis Had, Wilsenton, Decware, Elekit, Will Vincent st70. The Pass is 3k used all the others are less.

Have these Heresy been updated? Crites makes replacement crossovers and drivers. They will sound better than new. Add some sort of filter to your ethernet also.

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.
