Whats the FATTEST sounding Tube amp to warm up Lean speakers?


What would you say is the fattest, warmest fullest sounding Tube amp to fatten up
Merlin VSM's?

They are 8 ohm, and easy to drive. 30wpc would do.

From my understanding, through reading here, the Famous match with AtmaSphere s30 actually doubles up on the natural detailed and spacious yet lean character of the Merlins.

Which Amp would do the opposite - be a little forgiving and sweet in the higher mids and fatter and fuller in the lower mids?

Thanks

may not suit you but the price of ARC ref75’s on audiogon have to be one of the best deals i’ve seen. a truly great tube amp with plenty of mojo.
i’m no ARC fanboy but bought one to try out and very impressed and i’ve had some great amps. btw moving the speakers closer together increases mid bass output just as closer to back wall does the same. i bet you already knew this. good luck
just had a thought. a used accuphase integrated amp would give you tone controls almost guaranteed to be centered at 100hz(bass control)which is ideal for midbass enhancement. overall going to sound great as well. 
Dumbeat, 

I bought a pair of Merlin VSM speakers from Bobby in 1999-ish... I'd have to check the receipt to remember for sure.  He upgraded them once and they had better bass as a result.  In 2001, I bought a Joule VZN-80 amp.  Why?  Well, my wife and I went to the CES show that January and I'd heard the Joule stuff with the Merlins.  Hear that, like that, get that... It wasn't a hard decision when you've heard the solution.  Pay The Man. 

I am not an expert... but I do know the Merlins are a "damped" speaker design.  They don't need help from an amplifier with a high damping factor and tons of feedback to control the low end.  If you match an amp that is more inclined to low end control (high damping factor) it may sound "lean".  "My Merlins" are not "lean".  

My Joule VZN-80 has a dial to adjust feedback.  There is a reason why it's never been on anything but "all the way to the left"... ZERO FEEDBACK. 

If your amp is trying to bully your VSMs with too much damping, it will hide the magic. By the way... that BAM module makes the midrange you seek even better since it filters frequencies that driver can't produce anyway.  The BAM doesn't just help the low end... it also helps make the speakers more accurate by not asking them to do things it can't do. 

That's one thing I do remember Bobby telling me...
I'm surprised no one has mentioned HH Scott tube gear. Especially when people are mentioning Dynaco. IMHO Scott absolutely SMOKES Dynaco ST-70 in every way possible. If you're looking for that fat tube sound, and want to hear some "magic", or "emotion" in your music. Especially with a bright, or lean speaker. They fatten/smooth them right up, and are just amazing to me. I just picked up another one this past week actually, a restored 340B receiver from 1964.

First time I heard the Dynaco. I kept thinking. "This is it? This is what I've heard about, by so many people? Where's the magic?". And this was on a nice, and very rare, vintage pair of Jensen's I went to look at, along with the Dynaco. I didn't buy either. But oddly enough, the same seller had a B&K ST something, or other. I think it was a bigger model then the original 140. On the same Emotiva preamp, but playing through old KLH Model Ten's (which I've never seen before, or since), that blew me away. And my dumb arse, being new to this at the time, walked away without the KLH 10's that he was selling for only $75. I'm still kicking myself for that one.

I would also think about a parallel SET amp that's fat sounding (not a Mastersound Box obviously), or maybe an 845 SET. Some of them are fat too I've read. The parallel SET from Musical Paradise (forget the model) is supposed to be a little on the fat side, but have a really nice "you are there" sound. And I wouldn't be surprised if they had a good return policy. They're known for great customer service. It's a 55 watt per channel Integrated one. Oh heck, hold on, I'll find the link. Here you go.

Gets great reviews, at least from the few I've read, and again. The company does too. 

Whatever you decide. Good luck with your search, and I hope you have a Happy Thanksgiving.
