In a tube amp, it's the output transformer that limits frequency response. Tubes themselves function nicely at RF frequency, and so do transistors for that matter. With an ultralinear circuit (with transformer secondary taps for feedback around the transformer) tube amps with transformers can be made flat to at least 20 KHz, and it is arguable whether higher response is necessary, since neither CDs nor LPs have signal content above this. SACD and DVDA may have higher frequency signals, but the audible effect is also arguable.
Can OTL's drive ribbons well?
Seeking comment on ability of OTL's to drive mids/highs ribbons, specifically on Genesis II.5/300/350.Prefer to consider without zero autoformers as they have a reputation of bleaching sound(?).Can they do it without losing their special sonic ability of speed and organic liquidity? I guess I am really asking this question of the more affordable OTL's, ie.Transcendant, Atmasphere MA1 etc. If OTL's cant do it, which tubes can provide fast organic liquidity with dynamics at around $4000 and hopefully much less(new or used)-- again specifically driving ribbon mids and highs?
Finally does anyone use Cello duet 350 to drive ribbons?If so how do vocals sound?
Thanks and appreciate your comments
