Wood veneers would be interesting. The black can be a bit hulking, kind of like a Carnac stone in your living room. :-)

dear all, 
have anyone compared the sonic differences between Cube Audio Nenuphar vs any of Reference 3A speakers? just curious how do they sound since 3A do not use crossover in their main driver too, and with only a cap before the tweeter, i guess the soundstaging , imaging, speed, dynamics etc.. generally very similar ? Thanks for any comments.

as I looking towards getting a pair myself, I would like feedback on the following:
1. any suggestions on a solid or tube integrated amp not costing a fortune ?

2. for those who are using SIT-3, what preamp are you using ?
@david_ten I see that you are using Edensound spikes. Did you get the extra large solid brass spike for the front and regular hemispikes for the back ? In that case, did it match the original rack angle ?

SIT-1 Mono’s are supposedly superior to the Sit-3 on these speakers. I have both so look forward to seeing for myself down the road. There are numerous YOUTUBE Videos featuring these speakers and Flea Watt Amps from Tsakiridis,Tektron and other Foreign tube amp manufacturers...dont think any of these marvelous sounding amps cost more than 2-3K. DECWARE might be a USA alternative although they dont have any 2A3 amps which sound awesome on these.
@philipwu Philip, check out Srajan Ebaen’s very recent review of Aurai Audio’s M1 Classic speaker. At the very end of the review (bottom of the last page / Page 11), Srajan compares the M1 to the Cube Audio Neuphar.

I do not know if the Reference 3A speakers are similar to the Aurai M1’s, or if the comparison is apt,...but his short summary relative to the Nenuphar might provide insight.
