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

@david_ten 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

I can highly recommend using a TEKTRON 211 tube amp (integrated) with the Cube Audio Nenuphars! Before the TEKTRON I used a NAT Single HPS. The TEKTRON is much better!! This is an addictive combination!!

Good to see the Bakoon 13R and Enleum 23R now getting the recognition they deserve.

@V10 thanks for your comparison, very useful. What other amps have you had experience of my I ask?

I saw that Cube Audio has used Tektron amps at shows in the past. My problem with Tektron isnt the sound but the top plate on their amps starts pitting over time. Some call it Patina....I call it Rust Spots which is really ugly IMO.  They need to fix that before I will purchase one.

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