I've had an AVA FET Valve CF preamp in my basement system for about 5 years and it's been paired with an AVA 600R hybrid power amp. It responds well to tube rolling and I currently have 2 Mullard NOS 4024 (12AT7) and 2 Brimar NOS CV4003 (12AU7) that improve nearly all aspects of the SQ including tonality, soundstaging and imaging. Also it's been absolutely trouble free during this time.
Van Alstine pre-amplifiers
Recently read a post regarding Van Alstine tube based pre-amplifiers.
Sounds interesting . One of the reviewers ( on the AVA website ) suggested the pre-amplifier did not add richness to the tone of the music and suggested the soundstage was not enlarged. Otherwise a rave review.
Has anyone have personal experience with these tube based pre-amplifers?
My goal is to add tonal richness and improve timbre. Plan to run into a Leben amplifier.
Thanks
