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

Kevin,

My understanding is that the Model One is essentially a 6 ohm load. Am I misinformed? Be that as it may, I have absolutely no issues with the bass on my amp with its 8 ohm output, down to the limits of the speakers. The subs make up for the speakers' shortcomings, not the amp's. I hear no difference in bass extension between my PX25 and my Triton 300B amps, though the bass resolution is better with the PX25.

On the question of tubes, I just don’t like the TJ PX25 that Gordon swears by. I find it overly warm, too bloomy and rolled off. I think the KR tube is far more neutral, transparent and extended - at least in my amp. Maybe that means I don't like "real" PX25's? So be it. The KR tube in my amp is a stone killer. Get Joe Fratus' opinion as well of the two brands before you make up your mind.
Hi all,
After discussions with key Audiogon members above, and a few others, in addition to Joe at Art Audio and Gordon at Wavelength, I've made the decision to purchase an Art Audio PX25 amp! I expect that it may be shipped out late this week and arrive sometime next week.

Will keep members posted of my thoughts on it.

Thanks to each person who took the time to write thoughtful responses to this thread - I greatly appreciate your insights and experiences.

Kevin
Congratulations Kevin,

I beleive you are going to be very happy with the Art Audio amp. Joe Fratus is one of the good guys. Outstanding customer support and service. Look forward to your impressions. Happy listening.

Cheers
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.
