@sim_audio_nerd  Thanks so much for sharing your impressions from the audition at your dealer. Following what you hear and want for your system is the correct way forward. 

I look forward to hearing what you decide on for a tube amp paired to your Coincident speakers. Reach out to @charles1dad who will be a terrific resource in this area.

I agree with RIAA on what he shared in his post.

The XA 25, based on feedback, is bested by Pass’ First Watt options he mentioned [for this specific amplifier-speaker pairing].

Bakoon amp. Wow! I am VERY impressed with this amp.

@toetapaudio has been consistent in his feedback of the synergy of the Bakoon with the Nenuphars, as have others.

@ riaa_award_collectors_on_facebook The dealer is a low powered tube/high sensitivity speaker proponent. It was due to my request he paired the Nenuphars with the SS amps mentioned above. He is not a Pass Labs dealer so didn't have the SIT amps and only hooked up the XA25 from his personal collection so that I get a taste what the XA25 can do with the Nenuphars.

So I guess if I do go for the Nenuphars, I have to pair with lower powered tube amp. I am just a bit hesitant going all tubes in my system but maybe I need to get over my "tube fear".

@sim_audio_nerd,
Thanks for taking the time to post your listening impressions. A number of comments in this thread have touted the Bakoon amplifier as an excellent solid state choice for the Nenuphars. I do feel it’d be really beneficial to hear them with a good tube amplifier for contrast and different presentation. 

The Coincident Super Victory II is fairly easy to drive but needs more power than the Nenuphar. Which can be driven well with a 2A3 SET (3 to 4 watts usually).and a300b (Usually 7 to 10 watts).quite comfortably. With the Super Victory II I’d go with 20-25 watts or more. You have crossovers and seperate drivers to contend with. This is a non issue with the Nenuphar.

I use a 300b 8 watt SET amplifier however my Coincident Total Eclipse II are an easier driven speaker compared to the later model Super Victory II.
