Treble response with FR drivers Chip vs SS vs Valve

theoracle · 2nd January 2005, 08:39 PM

Hi all
Nelson Pass commented on Pg6 Oct 04 Audioxpress that valve power amps are often better with fullrange (Fostex, Lowther)
than ss in the top octave. To do with impedance and damping factor. Aren't Gainclones and solid state the same here?
Limited experience of FE204e, 206e, 167e with 3 ss amps have not been good with treble extension / bloom.
I know Fran G is enthusiastic with his combo.
Enlightenment would be welcome.

Cheers - The Oracle

FWIW when i first built a chipamp i used to listen to Lowthers and the chipamp really impressed me. I never really liked it on 'normal' speakers.

Lowthers with theirs " paper sound " realy show true quality of apparatus

. Let's go to the stone age, guys

Upupa - so that's a vote for valves?
Are you commenting on treble?

Valves have " sweet " trebles, which is good on guitar amps ( ofcourse with attack

), but combination with low input impedance SS or chip amps is problematic, 'cos in this case rise distortion. Probably better results give " medium power " ones, such as JJ's ECC 99 for example.
