OK, got it delivered on Saturday and played about 2-3 hours worth to make sure it was OK for me.
Initial impressions are
PROS
bass is improved - its a little tighter and noticabley deeper. Also the separation is improved, i can hear quite a bit more detail over my Denon, details like peolple breathing that i had not noticed before. The tone controls are a nice touch, and handy for poor masterings, so im glad i opted for them, that said it remains to be seen how much i actually use them.
CONS
i personally find the finish a little plasticky, considering my "budget" Denon had a full metal fascia, its a little dissapointing for what was a £1000 amp to have a plastic fascia. Its also a bit of an ugly brute, but i appreciate thats subjective - im not a fan of all the blue lights etc, i find it a little "busy". Shame as the CD6005 is actually rather pretty, and considering they are based on the same design....?
OVERALL
happy really, i knew about the aesthetics to begin with and i accepted that comprimise due to the functionality of the tone controls and the price point... need to play a lot more music to give anything meanigful regarding sound quality - and as my mrs paid quite a bit towards it as an xmas present she has demanded it go back in the box until xmas now lol. In Jan i will attempt to write some kind of a review. I think its worth the £580 i paid as an upgrade from the Denon, however it was not night and day difference, and i dont think i would have paid the original £1000 asking price... ive long been an advocate of diminishing returns, and again that opinion will be subjective. This will be my last amplifier upgrade i would imagine.
