PX-25 tube amp with Merlin VSM speakers?

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.

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.

Congrats! Looking forward to your impressions. From my time with the Carissa I think Art Audio amps are very fine music makers. Their build quality and aesthetics are outstanding as well.
