I have used the AVM-20 (ver 2.0) for over one year in a combined audio/video set up. I have been totally happy with it's processor, usability and general sound reproduction and incredible flexibility (replaced EAD Ovation). While in contact with Chris Johnson of Partsconnexion (www.partsconnexion.com), about upgrading my Sony DVP-S9000Es, I asked about upgrading the analogue portion of the AVM-20. Primarily, I was looking for better resolution out of the CD input for CD& SACD. In short, the upgrade involved soundcoat dampening material, replacing op amps, capacitors, resistors etc. that affected the main pair of balanced outputs and the 1 pair of RCA analogue input marked 'CD'.
This upgrade has totally elavated the performance of the AVM-20 as a pre-amp. Improvements affect cd, sacd and dvd performance. The soundstage is slightly larger with more depth and better focus. The timber of the various instruments are much more apparent (plucking of strings, richer tone, deeper bass, smoother violins, more relaxed sound, decay of piano etc.). More air around the various instruments and better pace. The most notable improvement is in the cd playback quality. Without changing anything else, the steely, gritty sound has all but disappeared (yes SACD is still superior). The same audible improvements are positively heard from music dvds and movies in general, especially those with well recorded soundtracks. Watching the Haunting again, there was so much more detail resulting in an even greater totally involving experience. I will be experimenting with different power cords (currently using XLO 10g), to squeeze some additional improvements. This is getting a little too long, but I wanted to share the dramatic improvement a cost effective upgrade can bring to what you already own. I now have a high-end pre-amp that also does home theatre with multi-zone capabilities. Who says you can't have it all. Thanks. Ed
ps The rest of the system is a Blue Circle BC32 (6 channel amp, also supperb), Mirage OM7, OM-R2 & OM200. Cabling is Harmonic Tech. Pro-Silway II interconnects and Pro 9 speaker cable.
