PX-25 tube amp with Merlin VSM speakers?


I love my Merlins and am mulling over an amp upgrade. I've heard of people driving Merlins with low powered SET and OTL amps, but, for example, the Art Audio PX-25 amp is only 6 WPC. Is that enough juice?

Thanks for any insights.

I might be better off looking at a 300B SET amp.


I've owned the Art Audio PX-25, AA Jota, and Welborne
Labs DRD 300B SET monoblocks at the same time. There is no real appreciable difference between the respective 6wpc and 8wpc of the PX-25 and 300B on medium sensitivity 90db/4ohm Jean Marie Reynaud monitor speakers.

Actually, there was no perceivable difference in power on
my much larger and more efficient 95dB/8ohm Cain &
Cain IM-Bens.

Which is better - PX-25 or 300B? Neither, it's just two
different views of the same sunset. Personally, I'd take
the PX-25. It is one of the most spectacular sounding
tube amps I have ever heard. One of the pro reviewers
coined the perfect term "as if notes are lit from
within". But, the 300B monos were just as alluring
in a different way.

I know a lot of reviews, and users, have claimed in the
past the Merlins and SET are a match made in heaven. I
think it's because of Merlin's fairly benign load of 6.5-8.0
ohms, with the two-way crossover zone at ~16 ohms.

I'd give the used PX-25 for sale here a try and see if it
works well in your sized room and musical priorities. If it
works, you will never hear anything like again. It may
need a new set of PX-25's because of low level hum in
one tube, which may not be audible in low/med
sensitivity speakers. That will set you back $400-500

If not, look for a Art Audio Carissa or Jota
Very nice system Dazzlingmd. Tell me, do you feel the need for a subwoofer using those Merlins? I am currently looking at speakers, and the Merlins are on my list, but I am used to running full range speakers, and my fear is that the Merlins low end performance will dissapoint. I've never owned a 2 way speaker in my main listening room, at 15 X 25 X 9 it is about medium in size, but I do not want a speaker that will require a subwoofer.

I'm also looking at DeVore Nines, Verity Audio Parsifal Encore/Ovations, Reference 3A Grand Veena, and Sonus Faber Cremona's. As you can see, the Merlin's are the only 2 way design that I am considering, probably due to the potential of the BAM. While I am not a bass freak, I do like a solid bottom end.

Cheers,
John
I am listening to my Art Audio PX-25 play as I type - fabulous, but with horns and not the Merlins. Instead of getting a new a new amp I suggest auditioning several different A/C wall outlets such as Furutech, Synergistic Research, and Oyaide. Very rewarding exercise.
