What To Replace A Pair Of Lamm Ml2 Monoblocks With? Need More Power

I think it safe to say that the ML2s are about the finest SETs made.
For many years I used comparable 4 chassis 3 Dimension Audio SETs. That was until I .also changed to a speaker that needed more power.
I learned a lot from my thread “ Is there a SS amp that can satisfy a SET guy?”. The ultimate answer was no. The musicality and warmth of a SET cannot be truly captured in SS. And push pull tube amps also don’t get there. However, if you love SETs, you call it warmth. If you don’t love them it is distortion. And the most significant comment in the thread was “SETs are like a sonic screwdriver that loosen the tone”. But SS amps “tighten” the tone to be somewhat too much. I learned, for me, the answer to my quest. Atma-Sphere OTLs. Simply, Atma amps are like two SETs that function in push pull. The result is a sound that captures the musicality and warmth of a SET with the detail of SS. I got my Atma M-60 amp on trial and knew within the first 30 seconds that I had found an amp that not only satisfies but excels. The 140 watt MA-1 would be the answer for you. But at a much lower price, the 60 watt M-60s would be good. Especially if you use them with Speltz Zero Autoformers which can raise the impedance allowing the amps to better drive your speakers. Talk to Ralph at Atma-Sphere. He is a real straight shooter and a great guy. He is very well known and respected on this forum.

Sorry for the double post. System’s fault.

Just wanted to mention that you should try the Speltz Zeros with the ML2s. You very well may then get enough drive for the Vandys!

Apologies for misspelling your company name (was in a hurry to get out of the house for a whiskey, ice-cream bar-prescription run before the Sunday grocery store feast VS fathom started here in West Hollywood).

Ypsilon hybrid. That's what some replace Lamm with. No idea how they would drive your speakers, though.
No one mentioned Allnic amps so I will. Again, no idea.
And final thought. Whatever you do keep the Lamm, you are unlikely to find a substitute. Yes, get rid of Vandesteen and find different speakers. 

Since you have Vandersteen 5's already, I'd look at one place to start and that's Richard's M5-HPA's.  I just got a pair and am floored by how great they sound.  As others have said, you need to match the speakers and the amps to get the best performance.

I own Quatro's and will now sell my Ayre AX5/20 with built in crossover, because these mono blocks are so good.  I've heard my Quatro's with the Ayre MXR's, Aesthetix Atlas mono blocks, Audio Research's 30k mono's, VAC's larger mono's as well as a few others and the Vandersteen amps are so far ahead of the others, that I'm floored.  

They are also a great size and don't throw heat like my tube mono's always have.  These are a very special amp as they have a ton of power for any room you will have your 5's in as they are a perfect match.
