Martin Logan speakers

jcder

I love ML speakers and have owned a few, but with the right amp if your to get the very best from them .
Most ML speakers dive down to less than 1ohm in the highs 10-20khz, this could very well reduce the sparkle and extension in the highs, using the AR tube amp/s it may sound distant and recessed. Also very hard for a tube is around 4.5khz were it’s 3ohm and -60degrees negative phase angle, this could reduce "presence" using tube as an amp.
Here is a shot of the Montis impedance/phase graph, which will be very similar to the Vista.

I was a Martin Logan dealer for many years and have personally owned almost every speaker they have made and have setup well over 100 pairs.

The Vistas are not that hard to drive, (90db sensitivity).  The ARC VT130 should have no problem.  That said, IMHO, the Martin Logans will perform better with higher powered amps, but decent tube amplification can be a wonderful thing.

In the right room and set up properly, Martin Logans are hard to beat.

I have owned several , one flow even in their best is  average capacitors . I had the 11A. Solen, And gum drop type nothing special I replaced with big Clarity CSA,on bass ,and Mundorf Supreme Huge upgrade. Why they are so cheap is beyond me 
myself and other have told them ,on deaf ears Maggie same crap.
even their $80k flagship cheap Mundorf Evo give me a break .
at least use the Black Supreme, , Silver Gold oil in flagship
all competitors use better Xover capacitors , resistors, And inductors are good , itmakes no sence.

Thank you all for these great comments.   Very informative, and much appreciated!

I have not listened to the ML Vista's, but came within inches of buying a pair of NOS Summit X's from a dealer.  I had heard the Expressions, which replaced the Summit X's and then listened to the Summit X's-- big mistake.  Martin Logan has not, and cannot, get the bass depth and timing right on these speakers.  Listening to a piano concerto, it was among the best sound I had ever heard-- from any speaker.  Put on something with a set of drums in it, or a bass guitar, and it goes right down the drain.  I walked away from a brand new set of Summit X's at $5,400 for the pair just for this reason.  The Neolith's, with their huge size (and more than $50,000 price), may have solved the bass problem.  But you didn't ask about spending $50,000 in your post.  Trust your ears :)
