hi, I suspect what you are hearing is lack of power with your tubes, lack of power or clipping the amp almost always sounds exactly what you are discribing. you should check the impedence curve of your speakers, they might suck up lots of power. if so you need a higher power tube amp. if you can afford it try a rogue audio m150 monoblocks, they put out 150 wpc and can drive most speakers out there. another thing to try is bi amping with the tubes on the tweeter mids, and your adcom on the bass, if the problem is lack of power , no feet or nos tubes are going to help, good luck , chrissain
Need Some Educated Advice...For a Newbie Tuber
Here's my simple system: Jolida 1000 w/stock tubes; Ah Njoe Toeb 4000 CD, upgraded; Infinity Kappa 8.1 (in perfect condition...owned them for years).
I love the overall sound of this system...my first tube equipment. Had Adcom 555 and Nak OM7 forever and ran them through my Infinity's....sounded ok, but just lots of power without finesse. Now, I'm hearing sweetness and ripe midranges with instrument sounds and staging that I never heard before on my discs. Bass is pretty adequate and soft and natural. Highs (vocals and full string sections playing forte) sometimes sound muddy and shrill...single instruments -- violin, guitar, brass, etc. are pretty clean al the way up.
Not sure where I could/should tweak or change to improve. Comments on system and advice would be most appreciated.
