The review was incomplete in a big way. The reviewer chose not to try additional tubes, which to me are the essence of the advantage of having such a product. One can change flavors by spending, just a small amount for two relatively inexpensive tubes.
To let that option go by the boards, when the question begs to be answered, was a tragic mistake.
I changed my tubes from the originals, and for all intents and purposes, I purchased a NEW amp.
I have mentioned before that this is the Gryphon, with a tube sounding pre stage--which, to me would be about a perfect match. I think the reviewer was simply a little 'lazy' by letting that opportunity go by.
Even though I am registered as a commercial user, I have zero affiliation with DK, as they will attest to, if asked.
I only like products which set new standards, in given price ranges.
I used this amp in the final stages of voicing my loudspeaker line, the LSA, after having used the wonderful Halcro line up of separates. To my surprise the sound was wonderful. "Musical" is overused, but the only appropriateword to describe my experience with this amp.
Nicksgem10s, mentioned that he would be interested in the viewpoints of three Audiogon members with more experience than he, well, having owned my own store, and worked for two VERY well known speaker companies, as Director of Sales for one, and President Emeritus,(an honorary title, as I am disabled.) Here is a gargantuan thumbs all the way up. Get one and don't look back. This piece is for real. Only people who can't compete, or are jealous of 'cheaper with better performance' could possibly make negative comments on this piece.
