I just bough a VAC Phi 200 to replace a McIntosh MC275 and think it was money well spent. The VAC is exceptionally musical and a joy to listen to. It does not have quite as gorgeous a mid-range as the McIntosh, but it actually seems more natural with better extension, better detail, and incredible dynamics.
But VAC is expensive, especially the preamps, and VAC gear doesn't show up for sale used very often. Hence there may not be as much discussion as there is for gear that frequently is listed for sale. In general, really expensive gear does not get discussed much. I cannot remember ever reading any owner impressions of Boulder amps, for example, nor do I ever see Boulder gear come up for sale used.
