Since you've declared your "interest" in manufacturer's retail audio prices, why restrict yourself to the relatively modest priced Tenor amp, why not go for the top?

There is also a Version 1.3 that you might like to critique.

Because I did not see a post about them that piqued my interest. I think I have now laid out my position on 'overpriced' gear without investigating other examples. Just to recap, that position is for the typical guy that posts on this forum, a blind listening test showing their audible supercity, or otherwise, is almost mandatory. But, IMHO, such high price amps are not targeted at those that frequent here. Legitimately, they are targeted at guys like Bill Gates, for whom that type of money means nothing, and can say, well at that price it must at least be good. They may also be targeted at those who want the mystique of an artisan crafted product like a RR, if that is how they were built. Perhaps less 'legitimately', but an equally valid market ploy, they are targeted at those that want a 'status' symbol.
And if you want to substantiate the "marketing ploy" angle, here's the Stereophile review of the above amp, and Stereophile is always known as just as shill for high priced audio gear, the more expensive the better.

And if you don't like Stereophile then you can go with this review, if you like Positive Feedback.

I have never been a 'fan' of Stereophile or other related magazines. I read and enjoy them, but take what they say with a grain of 'salt'. Only reviews that include blind listening tests get my guernsey as top flight audio journalism eg
http://www.stereomojo.com/SHOOTOUT2007INTEGRATEDS.htmAlthough I rate the above highly, IMHO it could be 'improved', eg the panny was fed a signal from a preamp - not from the digital out of a transport, which is how any sane person would use it. I also would like to see non blind evaluations done in a persons home on their equipment, interspersed with blind evaluations, done over a period of months, to see if acquaintance with the equipment changed the outcome. I do not know the background of the panelists in the steromojo review, it quite possibly includes the type of people I am about to suggest, but I would also like to see people that design the type of equipment being reviewed by ear - people like Hugh who designs his amps by ear. To me, such reviews would be instructive not just for the reader, but for those taking part.
Thanks
