Meniscus tears are no fun.  Lived with one far too long.  Wish I'd gone to the surgeon first thing.  I suppose that's deemed an elective surgery right now?  Good luck.

My bad, I didn't understand your point at first.  Yes, the wood strips do close off the space front and back between Platform and bottom of speaker.  And you're right, that space was no doubt tuned for the size and output of the port.  I'm going to do some A/B listening with and without the wood strips to see if I can get a handle on what it's doing to the bass. (Ok, I have to admit when I first put the wood under the speakers my ears gave a double thumbs up and they haven't moved since.) But I have to say when I was listening to the Symphony Fantastique the other day (at near live level) I was amazed by the depth and reverberation of the kettle drums...so I don't think it's diminishing the bass...

On another note, I ran into the Townshend Super Tweeters I used to use with other speakers in my storage closet.  I think I'll experiment with those.  I remember SE effusing about the addition of omnidirectional super tweeters (forget the name right now) on top of the Nenuphars.

This makes me sound like I'm unappreciative of the Nenuphars as is.  Hardly.  It's more like having a hyper sensitive instrument that responds to everything it interacts with.  Fun stuff.  

Has anyone tried a Valvet amp with a Nenuphar?

@rwpollock   I've had an interest in Valvet for some time and came close to purchasing the A4 instead of my Pass Labs 30.8 to drive my previous speakers.

I just took a quick look at Valvet's website but couldn't find the information I was looking for.

I recommend reaching out to Alfred (the importer/retailer) and Valvet directly to find out the following:

- Feedback (preferably zero; or very low levels)

- Damping Factor (the lower the better)

If the above holds, I can see Valvet being an alternative along the lines of First Watt, which (as you probably know) has proven to be a terrific pairing with the Nenuphars.

I've sent an e-mail to Alfred at Highend-Electronics. Will let you know what he replies.

Reference coupling to Townshend Podiums. This is a good thing I believe but difficult to achieve in practice. At the moment I have only gone as far as fixing down the cups with industrial double sided tape to the Podiums to stop sliding. It also means I can change from 10 to 8 inch Nenuphar’s using the same Podiums by detaching the cups and repositioning.

Any material change under the speakers ( or under any piece of equipment for that matter) will change the sound of course. If I were to make new block feet, out of wood for example, then I would make use of the existing threaded inserts in the speaker bottom and fix them using counterbored threaded bolts. The feet would then be fixed to the Podiums with DS tape or even better ( but more extreme) drilling a hole and fixing with screws from under the top plate. Candidates for best feet material: perhaps Maple, Ebony, brass?

Regarding amplification compatibly with the Nenuphar’s I just want to emphasis that the little (but giant in performance) Bakoon 13R should be added to the list of suitable amps imo.
