Does anyone use the Silverline Audio SR 17 speakers? If so, how do you like them?

I've had the "non plus" Preludes for a while and they are really great speakers. They're voiced for a relatively even tone that works for me with non screechy treble and great mids, and although the specs claim more bass than they actually produce in useful amounts, this isn't an issue as I use a couple of RELs with them. Tube amp magic in a relatively large listening room...Alan Yun knows what's what. 

The 17's are an excellent speaker and, as you have observed, they rarely come up for sale. I'm still waiting for a pair with the ESOTAR tweeter to appear. (I already have the Bolero's but am looking for a different tonal balance in a second room). If/when I decide to abandon that wait I would consider the Prelude Plus' currently selling for about 2K. 

I called Silverline Audio yesterday (7-5-2016) and actually spoke to Alan Yun. My question to him was about speaker placement for the SR-17s. For my room size (13 X 13 X 8) he thought between 2 and 3 feet from the rear wall and 2 feet from each side would be ideal, and no toe-in necessary. He considered the dimensions to be a mid-sized room, and thought the SR 17s would be a perfect fit. He was very excited about the latest iteration, the SR 17 Supreme. He thought the Dynaudio drivers were the best he has seen for these speakers. He does his own crossover and is justifiably proud of it. I'm In!
