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

There is definitely a distinction between acquiring a "natural" patina and rust. 🙂

@eric5kim Eric, both of my 2A3 amps were designed and built by Scott Sheaffer (Found Music). I picked up the first pair of monoblocks used. They were built for member Mike Lavigne. I commissioned the second set. They are a 4 chassis build. You can see the amps and their power supplies in my virtual system page.

I listen to electronic music fairly often as well as large orchestral music; and rock to a lesser degree. I find that my system delivers with all three genres. If anything, it is my room (which is mostly untreated) that exerts a role once the volume levels are 95 dB and up.

As a reminder, I have the V1 Nenuphars.

Much more important than raw power output numbers, in my estimation, is the quality of the amplifier build AND how well the incoming power (into the audio room, conditioning if used, and power cables) has been addressed. Component and cable isolation also factors in.

Members who are more versed in tube amplification, like @charles1dad and​​​​@larryi , may be worth reaching out to... or they can comment.

High dB peaks, especially with classical music, and the level of power needed before distortion and clipping, is covered in many threads. Many advised me against the 2A3 amps I chose. My experience has proved otherwise, with respect to the Nenuphars.

which 2A3 are you using? does it have enough headroom for large orchestral works/rock/electronic music? If listening at 88db need at least 10db of headroom for peaks

@david_ten  Thank you David. Those 2A3's are a beauty

Eric, I also owned the Melody I2A3 integrated amplifier which was paired with Vaughn Audio Loudspeakers. That is the extent of my exposure to 2A3 amplifiers.

A reminder. While dusting off the Nenuphars this morning, I noticed one of the four outer screws on the driver 'front assembly' was very loose. They are T-25 screws.
