PX25 SET amps-Art Audio, Audion, Wavelength???


Fellow Audiohpiles,
I am considering a SET amp and in particular a PX25 based amp but to date have only located 3 brands:
* Art Audio PX25 (US$6,500)
* Audion Silver Night MKII PX25 (US$5,495)
* Wavelength Saturn PX25 (price?)

Are there others you recommend I investigate?

Of the three listed above how do they compare - is one head and shoulders above the others? I know this is subjective but any insights would be appreciated.

thanks very much,
kevin

Nicely done Kevin. Wait til you see that Art Audio in a dark room. The 2 things I look forward to with my Symphony II is turning it on and waiting for night. Joe Fratus may have a few equals but none better. Enjoy.
Well, the PX25 arrived today . . .
In a nut shell, it was worth the wait. Joe at Art Audio has been excellent to deal with - very customer focused and a man of his word.

In short, here are my initial thoughts based only on one night of listening (thats my caveat):
* very, very detailed - Track 3 on Jacintha's "Here to Ben" CD has an odd clicking sound at the 9 second mark just as she begins to sing which I've never heard before!?
* great soundstaging - Brian Bromberg's "Jaco" tribute CD has an amazing solo on track 9 in which you can clearly place 2 different sounding basses just inside the right and left speakers trading licks back and forth.
* very good bass control and deep too - take Bela Felck's track 4 from the "Flight of the Cosmic Hippo" in which Victor Wooton plays some kind of a double-down device alowing him to play an octave lower which gets down in the 30'ish hertz I'd guess. Or track 3 from Michael Wolff's CD of the same name ("Michael Wolf") in which a synth bass is one of the lowest basses in music I've heard.
* for 6 watts, very good dynamics - Jacintha's voice builds to a double forte on the "Here's To Ben" CD, especialy on Danny Boy and Somewhere Over the Rainbow tracks.

And it plays plenty loud for 6 watts . . . my First Sound preamp isn't much above 4 on the volume dial . . . probably more to do with the preamp's high gain. . .

Thanks to all who helped me find this very fine product and company.
Kevinzoe,
Well... you've had the PX-25 SE Amp for about a month.
Lots of us wonder if things are still sounding great!
Gee some of these asian over-seas SE amps look good & also inexpensive. Not sure how they might sound.
Did you try any?
Regards
Ron Glaze
Ron - thanks for your post reply. I didn't come across any asian SET amps that caught my eye or that I found here to audition, so no I didn't hear any for comparison purposes.

Yes it's been a month already and the amp still sounds as wonderful as it did from day 1 . . . Now I'm experimenting with the 4 and 6 ohm taps on the amp and also the Sophia 274B.

Are you interested in SET amps? Any Art Audio specific questions or anything else I can address?
Well, this thread is now over 13 years old, but as one of the original contributors I just had to update it with my PX25 experiences in the intervening time.

The Audion PX25 Silver Night MkII that I had back then is still driving my Fab Audio Model 1's flawlessly. It's playing right now, as a matter of fact. It was out of service from 2010 to 2018 due to my lack of space for the system, so it just sat in the basement collecting dust along with the rest of my components : a Tom Evans Vibe/Pulse preamp, an Audio Note 4.1x Balanced Signature DAC, my Fabs and an ACI Titan sub.

I just set it all up again recently following my wife's death, and it is blowing me away as in days of yore. I guess almost a decade of listening to nothing but computer speakers made my ears hungry for music, and even the arrival of hearing aids hasn't dampened the pleasure. After a re-tubing the amplifier is rock-solid, and behaves as though no time had passed at all. I had forgotten just how damned good that amp is.

Kevin, if you're still out there I'd love to regain contact. I still remember my visits to your place fondly.

Here's to Audion, the PX25 tube and music.
