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.

Hello Dazzling MD,

Here is my two cents with respect to your question.

I have owned the exact speakers that you have currently and powered them with a variety of amps. I would offer the suggestion that you investigate the AUDIO MIRROR 45 watt SET amps. They most definitely would have enough juice to power the Merlins to whatever levels you might desire.

I have a room that is similar in size to yours at 14' x 20' and the AM's really made beautiful music with the Merlins.

They are basically bulletproof amps (mono blocks) as they are self biasing as well as they will shut themselves down if overdriven. I never got to that point with them but did with a pair of Harbeths that I owned which are less efficient than the Merlins.

The AM's use a pair of 6c33c power tubes (which is what BAT and Joule use) and a 6sl7 for an input tube and 6sn7 for a driver tube. The amps is very receptive to making a substantial improvement in sonics from stock with adding NOS 6sn7's and 6sl7"s. I would also recommend the VT99 as a driver tube which is even better IMO than the 6sn7 but it does require an adaptor.

These amps are hand made in Houston by a gentleman named Vlad Bazelkov. He was great to work with and made mine custom with balanced instead of single ended inputs as well as adding V caps instead his stock caps.

These amps really knocked it out of the park with a huge soundstage and excellent dimension and detail without a hint of harshness. You already have a great front end with the Allnic so the sonics should be spectacular.

I hope that this gives you something else to think about as an alternative to the 6 watt SET you had inquired about.

All the best,
