300B Tube Amps with 15/16 Watts Per Channel?


Felix Audio makes the dual 300B amp "Lybra"--are there any other manufacturers of that gear?.Does anyone have experience using two each 300B tube amps modified to be two monoblocks with 15/16 watts output power each? If yes, did you hear any difference in the exquisite 300B sound other than more power? All experiences and thoughts appreciated. (Yes, expense is already noted)

@atmasphere thanks for the info. Wonderful explanation. Yes, my speakers Cube Audio Nenuphar is a single wide band driver. The manufacturer recommends amps with 0 or low feedback design, which will also have low damping factor. I have gone through some amps, and fine these recommendation matter a lot when it comes to the bass performance.Ā 

The type of iron is dependent on what he have on hand but it will be very good with whatever iron he uses šŸ˜Š

That's cool. Do you mind sharing what speakers are you pairing with it ?

I have been using these mono's with Liberty Audio X-VOX, which is a parent company of PBN Audio but they are being replaced with Qualio IQ which will arrive next week šŸ˜

@wig well, I have been meaning to try the Qualio IQ. Both Cube and Qualio comes from the same designer Grzegorz. They have a YT channel (Virtual Hifi) and the performance has been stellar. However, I was under the assumption the Qualio would need some amount of power to perform better. Have you spoken to the Qualio folks to see if low wattage 300b amps are a good match ? It would also depend on listening room and how loud you hear but I can't wait to hear your feedback on the Qualios with the Otomon amps.

Follow Greg YT channel on a regular basis šŸ˜Š

No problem with Mono's driving Qualio and they are more powerful than my 100 Watts Class A/B KT88 Amp šŸ˜
