Audio Research VS110, VS115?

The VS110 and VT100 are out of production, so if you want a new amp then the VS115 is the way to go. I have owned the VT100 amps and listened to the VS110. Imo, going from the VT100 series to the VS110 would be a major step down and backwards. The VS110 is only single ended whereas the VT100 and the VS115 are balanced designs. The VT series sounds awesome! I plan to get a VS115, but have not listened yet, but I think and hope that it will preform as well as the VT100. The VS115, imo, really is the VT100mk3 but with an open design instead of being put into a box. I think they did this to avoid overheating issues. I did not ever overheat a VT100, but I can see where people would try to put them in a rack and overheat them.

The VS110 may sound good too, but the VT100 has more of everything. More detail, more tigher focused bass, deeper bass, more midrange bloom,more subtal nuances to notes, more quite space between the actual music notes etc, more soundstage. It takes me quite a while to really notice these things. I need to listen to allot of recordings to really hear and notice. It takes a while to really get to know the sonic signature of gear. I need to live with it for a while and try different speakers, cables etc.
