Small balanced monoblocks

I would add Clayton M100 monoblocks to your audition list. Output is rated at 100 watts / ch. class-A. It has both RCA and XLR inputs, and its relatively small size would fit your living room as well. Check out www.claytonaudio.com for more info.

Happy Listening!

I second the opinion on the Classe CAM-350s, my present amps. But if your speakers don't need that much power, before the Classes I had Pass Aleph 2s, and they were wonderful. There is usually a pair or two used on Audiogon.

Not sure if you want to keep with SS amps or not, but bear in mind that your speakers were likely voiced w/ tubes. Pat McGinty seems to like the 6550-based 100 wpc Music Reference RM-200 a lot (has his own, demoed the Nightingales at CES w/ them a couple of years ago, plugs it at the Meadowlark web site). It doesn't fit your bill as it's stereo but gives you an indication of your speakers' designer's thinking. Also remember that all Meadowlarks are designed to be tube- and modest power-friendly. Some of the above recommendations, while great amps, are overkill for your birds, which should sing sweetly around 100 wpc, assuming high quality power.

There seems to be some degree of consensus among Heron owners at Audio Asylum that the Herons prefer EL-34 based amps. The whole-hog answer to this would be a pair of the new Cary V-12s (though most of these are stereo amps, Cary does wire them in mono as well). 100 watts each in triode mode, 12 EL-34s per side. Unfortunately, they are not at all small and go for $8K (per pair) new, though, so probably not the best answer - just the best LOOKING answer.

Another option is the VTL MB-125 monos. 4 EL-34s, 55 watts triode, 100 tetrode, compact; only drawback is no balanced inputs. VTL's 6550-based MB-185 Signatures have balanced inputs and more power (105 triode, 165 tetrode) but are definitely bigger (std 19" width, 9" high).

I've gotta second the VK-60 suggestion as well given the rest of your components. This is another amp that Meadowlark has used at CES and gotten (claimed to, at least!) great results with their speakers.

Check out Pass Aleph 2 monos. 100 watts single ended. I use them with a set of Meadowlark Kestrels and I think they are a fantastic match. BAT VK60s are very nice, but they are huge and will heat a small house. There is a set of Aleph 2s on this site for sale at a very reasonable price.

I am intersted in hering the Plinius Class A stuff.Posts on audioreview.com are ga ga.These Bel Canto digital amps are getting the rave too.Youmay not need to spend that whole wad and get something decent.Oh yeah one guy who owns a shop say's the big McCormack is the best amp out there bar none and I think it fits your price tag.Hell with that budget I'd dump the Herrons and go deeper in theri line or give yourself some options with a new amp and start auditioning speakers not that the Herrons are anything to not like.But that's a big amp budget considering what your going to end up hooking 'em up to.Budget concious?Check out the Monarchy class A amps.Like Rogue evrybody thrwos in word "value" when they talk about them.
