Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

If you remember, Cube Audio didn’t like the pairing of the V1s with 300B based amps

I was under the impression that Cube Audio specifically had lower power, high output impedance amplifiers in mind to pair with the Nenuphar characteristics. 300b/2A3/PX 25 etc were the intended targets. Thus the very damped driver via very powerful magnets/motor. Exactly why an amplifier with high damping factor is not seen as advantageous. A good quality 300b SET would seem an excellent Nenuphar partner.

@mikeg  Mike, my memory might be failing on this but I don't remember Cube "not liking V1s paired with 300B amps."  What I do remember is a preference by Cube Audio for 45 and 2A3 amps. If you have more information on this from Cube, please share.

Based on my experience with the V1, the ~8 watts of output, typical of 300Bs, is (per my estimation) the bullseye for 'ideal' SET power to drive the V1s. 

I'd expect a high quality design / execution of a 300B amp to be linear and neutral and be an effective pairing for the V1s. Chosen 'voicing' of the specific design, per the owner's preference, is an obvious factor.

@charles1dad ditto. I was under the same impression. Inquiring minds want to know what backs up that statement.

@juanmanuelfangioii

In all candor I don’t believe there is a backing up statement. Certainly due to personal taste preference one might prefer a 45 /2A3, nothing unusual there. By the same token other listeners may prefer the 300b. Normal variance depending on numerous audio system factors.

Here's some food for thought:  I think this a question for Cube Audio with respect to the V1 and they will see it as a mute point.  Why did Cube Audio have a list of compatible amplifiers when they offered the V1s?  You don't see a recommended list for the V2s. Why did the Mono & Stereo Review state: "For tube amplifiers, Cube Audio recommends such designs based on 2A3, Px4, 45 tubes" and not 2A3, Px4, 45, and 300B tubes.  Have you ever seen Cube or Refined Audio specifically demo with 300B based amps? I remember addressing this exact question at some point in my search.
