PX-25 tube amp with Merlin VSM speakers?

Agree with Darkmoebius. I had the PX25 for a short while. Loved what it did but was just a few watts short of driving my Zu Definitions to max capabilities. I ended up with the Carissa at 16 watts, and that did it for me.
Anyway, (FYI) there is an Art Audio Diavolo up for sale on that other popular site for $2300.00. That comes in at 13 wpc.

FWIW, I had the Art Audio Carissa which had the attenuator. On it if you opened the attenuator completely it was removed from the signal path. I used it in this manner with a pre-amp. I believe all the AA amps are configured this way that have the volume control.

The Carissa was ont of the best amps I have owned or heard. I wish I could afford to get another one. I really miss that amp.

Ha anyone compared the Carissa to the Diavolo? I've heard great things about the Carissa but don't know much about the Diavolo.

I've never heard the Diavolo but FWIW, I've spoke with Joe Fratus (he used to be the man behind Art Audio line in the US) a couple times and I got the impression that the Diavolo was his favorite amp in the lineup.

Dazzlingmd, check out the reviews at 6moons. They have write-ups on the Carissa, Diavolo, Jota and Symphony.

The late John Potis, one of the best reviewers wether on the Internet or print, wrote a perfect review of the Carissa and described it sound and character beautifully. He absolutely nailed it.

Also, I do believe Brf's comment has some value to it. Good luck with your amp search.
