@inna with the risk of sounding self-serving, but you might find this interesting, I have a pair of GoldenEar One.R speakers in like-new condition for sale.
Wonderful speakers with built-in active subwoofers (*) and DSP. I’m sure you can find a lot of reviews online.
(*) this would also take a lot of load off your tube amp
MSRP is $7500 and I’m selling them for $3200, plus if any shipping.
I am based in Raleigh, NC but can ship. I have all original boxes and accessories.
Just shoot me a direct message if this is something you’re interested in learning more about.
