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

@ david_ten

I have experienced the same phenomime you have eluded to in your very informative posts. Four months ago, I never heard of a 2A3 or 45 DHT until an EE friend/designer mentioned that it is the most refined tube one can acquire and that started the ball rolling since he mentioned that 2 Watts would drive my 98 Db+ speakers...

Two months later, Triode Lab 2A3 Monos 4.5 Watts with Hashimoto Output Transformers arrives and the clarity and dimensionality is unmistakable especially if you have efficient speakers of 98 Db+.

None of the KT88 Amps or SET 805 with 300B as drivers I have owned has the refinement, separation, depth, sound staging, transparency or the flow of sound that those DHT provides, it’s just magical and I believe the sound quality is related to its simplistic design.

I also have many friend owning 2A3 Amps and have a collection of NOS Tubes and the verdict is the JJ 2A3-40 and that’s what I’m using with some Shuguang 2A3C as back-ups which are quite good as well.

The JJ 2A3 40 has a reputation as a very good sounding tube for reasonable cost. I be quite curious as how it compares to the EML 2A3 solid plate (SP) David currently uses. David if you ever decide to try the JJ I’d be interested in how it fared against your excellent (My opinion) EML in your high resolution system that seems to easily bare all sonic nuance/subtleties. This would informative.

That would be an interesting comparison and have heard some talk about the new Psvane Acme Series 2a3 that suppose to be better than everything...but they all sound different in the many typologies that are available.

@wig  I'm with you, as you know! : )

The Nenuphars are 92dB / 6 Ohm (going by memory here) and the 2A3s avail themselves with distinction. Surprising, because on 'paper' they would not be advised. 

@charles1dad The EML SPs replaced the JJ 40s Scott’s Found-Music 2A3 amps came with (per the seller’s offering). In other words not stock. Buyer would specify if the amps were to be purchased new.

Not even close, in terms of my preference for the EML SP over the JJ 40s. Having said that, my amps / system sounded very good with the JJs. They are a terrific value.
