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

Re the different solid state amps:
I wanted to note that the main difference for me was that the FirstWatt amps had a bit more of the mid-range-icity that is a major attraction of tube SETs.

I realize that the 300b tube is being discussed in the context of utilization for preamplifier section duty. I've only used them as output tubes in power amplifiers.  I do believe that to get the best from this splendid (My opinion) tube you have to use the premium level options which admittedly are expensive (But worth it).

Elrog, EML,KR, Takatsuki,  these are going to yield exceptionally good sound quality. Worth the cost if you have the level of audio systems/components under discussion here. The Nenuphars will easily reveal the improvement these higher tier 300b tubes provide. I wouldn't cut corners.

Thanks Robert for the reply.

Currently I’m using the Bakoon 13R with a Bakoon dac, which is out of production. We should see a new dac from them at some point.

Since we’ve been discussing amps...here are two short clips of the Nenuphar being driven by Absolare’s Hybrid Integrated SE. Posting since I don’t recall mention of an Absolare pairing in this thread. Please correct me if that isn’t the case.

Courtesy of Dükkan Hifi, a dealer in Turkey. Note the use of Townshend Audio Supertweeters. There is a comment regarding their negative impact on sound quality, though Dukkan mentions in-person listening for a better / correct evaluation. I personally don’t see [hear] the need for the addition of supertweeters. Curious, nonetheless...Anyone using them with Cube Audio speakers?

For those of you who have the Nenuphar Mini speakers, here is a longer (mix) clip from Dükkan Hifi .

Driven by the Aesthetix Mimas Integrated Amplifier.
