DartZeel compared to Pass Labs XA-160/200's


Has anyone had the pleasure of auditioning both the DartZeel amp and Pass Labs XA-160 or 200 monoblocks? They all retail for around $20000.00 and are true reference pieces. If so, what did you hear concerning the sonic signatures in the different amps and what other gear were they being used with. I'm very interested because I will being to try to set up home auditions of both amps in the near future and both have gotten raves and are supposed to be the most "tube-like" SS amps there are, offering both "warm/sweetness" of tubes and at same time have the slam/extension/clarity of SS. Thanks in advance if anyone has this information based on their own listening experience.

Branimar, only 300 hours on the dartzeel. really if it does not sound competent at 300 hours it will never souud good. But you all ready know that right:)

ps I'll give everyone a secret tip, consance cyber 800. 78 watts of pure tube heaven.

do you think this will drive Amati Anniversario. Is it really that much easier to drive to get effortless music from them.? ie compared to Vienna Mahler?
Downunder -> I heard the Aniversarios driven by 40W tube amp (using 4xKT88 tubes). The combination souded excelent, so I assume the new SFs are not a that difficoult to drive.
Downunder, as Elberoth2 said Anniversario's could be driven with lower power tube amp. But, from my experience you will need 70W tube amp or 100W ss amp for start.
Tube amp should be able to handle 4ohm load as well as ss amp. We all know that some amps have a tough time with speakers that are droping below 4ohms...
I have had the Dartzeel for about 3 months and it came broken in. Only recently have the full potential seem to bust out. It extricates more music than any amp I have EVER owned. The Dartzeels 100 watts sounds more dynamic and powerful than amps with a 300 watt rating(tube or SS). An amp that it rivals would be the audio research-600. You owe it to yourself to check one of these amps out
the dartzeel is strictly flavor of the month.not what one would hope from a major investment. the pass labs monoblocks have consistantly been among reference quality.
