This system has been evolving for years, very s atisfied with the sound now on both vinyl and cd. The Unity Audio Signature 1 speakers have been in the system since 1993 and I have no inclination to change them out-extremely musical, image like a good two way monitor but yet have great bass due to the down-firing 10 inch woofers. But who knows, right?? LOL
That's a beautiful room and very nice system! Do you find all the glass interferes with imaging/other attributes? Have you thought about putting a draw curtain (traverse rod) back there so that you can close it up when you listen?
