@soix and @oddiofyl - That would be ideal, but as I mentioned above:
these are custom programmed and a universal remote will not work with the preamp. As of now, he says he can be contacted if one needs to buy a replacement remote, but when it's down to one guy and probably a limited supply of remotes....
@rmdmoore - thank you for that - I'd like to hear more about that LS-100. I've gone on YouTube and Dan Wright has videos talking about the LS-99 and the LS-300, but there is nothing I could find on the 100. I guarantee any remote it has is more substantial than this - I wish I could post a picture of it, you'd laugh - and it would probably be able to be programmed with a universal remote.
Again, thanks to everybody contributing suggestions; I have a few thousand dollars at the Music Room from another unit I'm returning (not a preamp) and I'd like to get something new or used (whether in stock now or likely to be in stock soon) from them to apply it to. They do have a number of those suggested.
Any thoughts on McIntosh tube preamps in that general price range? I've never owned any McIntosh gear but the descriptions of some of them on forums and reviews sound like what I'm after too, and some even have a DAC and phono preamp, which may or may not be up to how I hear what I currently have.
