What new amp for my Merlins

If heat is an issue, the Berning is the way to go. It runs cool, takes up little room, and tubes last much longer than almost all other tube gear.
Berning gear also holds its value nicely, so you won't have a lot of risk if you decide to move in a different direction later. Cheers,

Spencer,
Did you use the Bernings as monos and what pre?

Jay,
I had a stereo Berning that I used with 3 different preamps. First, I had a Cary SLP-2002(very flawed). Then I used a Joule LA-150(paired w/Pentagon PS3 phono stage), CAT SL1 Mk III w/internal phono, finally a Joule LA 100 mk III(& OPS1 phono). Others have reported First Sound preamps as a good match, too.
The LA150 had the best line stage, but phono performance drove my changes. Severe unusual RFI issues in my new room led me in another direction(i.e. all balanced gear), but that shouldn't affect your thinking.
Feel free to contact me offline if you'd like to discuss by phone. Cheers,
Spencer

I called Bobby and gave him four choices that I had, not including Joule-Electra, and hands down it was the Cary V12R. He recommended the Six Pacs as well, but I wanted the 100 watt UL option. I drive mine with Raytheon 5751s instead of the 12BZ7 (black plate, windmill getters) and a First Sound Presence Deluxe Mk II ... a killer combination for my TSM-MMs.

Manley Stingray,in 25w Triode mode.Siemens ECC 81 tubes.No complaints from my side... !! Its a great combo,but thats already very well established.

A great amp for the asking price.
