Hello: I have a SuperPas 4i preamp. I have had a CJ PV10al and a Modulus 3a also. The AVA remains in my system and the other 2 are gone. The CJ was a close contender and I could have kept either but for the $$ the AVA is pretty hard to beat and with a tube phono included it is a hard pre to beat for the $$. I also have a Fet hc350 amp driving Maggie 2.7s. The AVA hc amps are a brute and are a great amp. As for service AVA is nearly unbeatable. If you mail AVA with a question you will likely get a reply very quickly, even on the weekend. The reply will probably come directly from Frank himself. That is pretty much non existant customer service from anyone else. My experience with AVA over the past 6 years has been great. A high end product that AVA and Frank VanAlstine believe in and excellent service. Super way to run a company .
