$3000 stand mounted speakers?

Lots of options recommended here for monitor speakers.
Of the suggestion here for $3k, these are the ones that initially intrigue me as a step up from the ProAc Table 10 I've been considering at $2k.
They would look nice in our place too, w/o taking over (WAF).

Omega Super Alnico Monitor
Dynaudio Special 40
Totem Signature One
Reference 3A de Capos (wood veneer version)

As a purchase w/o hearing, I think I'd have an easier time reselling if it doesn't meet my expectations too.

If you'd be open to purchasing a pre-owned speaker, I'd recommend you look at the Totem Fire monitors.

The Harbeth P3 ESR will sound great with your EL34 tube amp. I have owned both the standard model and the anniversary edition. A perfect fit for that size room!!

Another recommendation for the Watkins Gen 4’s. Check the reviews-$2495!

Pretty big room for a "a small monitor speaker." My only suggestion is to look for something very efficient; it might help to fill the room. If you want specific recommendations, consider the AudioNote AN-K.
