Thiel loudspeakers are the most with equipment like yours. They completely disappear with some of the best digital. They have the widest and deepest soundstage that I have ever heard. You want to stick to models from the 2.3 and up. The 6 and (5i older model) and 7.2 are certainly magical and musical. Good equipment is not wasted on this speaker at all. Lots of space is required to sound natural. My current setup is:
Sony SCD-1, Theta Gen VA, Pass Labs x-2 , X-350, Thiel 2.3s Harm Tech Pro Silway II, Pro-9, Audience Power Chords.
I also have to worry about my room measures 12 x 15 x 10 a non dedicated or closed listening room. I am using Jon Risch DIY acoustic panels (on the three(3) 1st reflection points and six(6) smaller panels on the front wall; these have made the greatest impact on sound stage depth. I also use 4 Jon Risch quick & dirty DIY bass traps. All of my materials cost less than $75.00. No tools involved. The Jon Risch DIY acoustics far exceed my expectations. Jon Risch is on the Audio Asylum. Under the Tweakers/DIY Asylum.
Enjoy, Dave
