Tobb...sorry to miss your question, I've been off the boards for a more than a week. The Edge NL 12.1 when it was new retailed for a little over 20K if memory serves but you could get it for a few thousand less easily. Now, when they pop up on Audiogon, which is extremely infrequent, they are posted for about $6K. The NL 10.1, which would be more than sufficient for driving AERIS or V's top-end are also not frequently offered, and can be had for a bit less. The 10.1 and 12.1 (the .1 are the versions to get sonically) are fantastic SS amps that don't sound solid state (to me, IMHO).
There is a member who has a pair of Tom Maker's new NL14+ monos offered for sale on the Audiogon right now for a price that is beyond a bargain. The NL14+ and NL14 stereo are Tom's next-gen refinements according to what he told me of everything he was doing with Edge in a more cost-friendly package. Being they are monos you pick up the need for another amp-stand and an additional powercord but if I were looking today, I would definitely pick them up!
