What piece(s) of equipment would you most like to try?


If you had the opportunity to demo any equipment out there what would you try? I have several in mind but here is my initial list...

darTZeel NHB-18NS amp
Burmester 911 MK III amp (ok and since we're going for gusto the 909 also)
Ayre MX-R mono block amp
Vienna Acoustics "The Music" speakers
Sonus Faber "Stradivari" speakers
Legacy Audio "Aries" speakers
Atma-Sphere MA-1 mono block amp
ARC Reference 250 SE mono block amp
128x128falconquest
Being most a low-powered tube fan, I would like to try something completely different, such as the YG Acoustics Sonya speakers with Bridge Audio Labs amplifiers and linestage.  For phono, the Lyra Connoisseur phonostage.  Now, how do I get the $500,000 or so to make this possible. . .
After hearing lots of talk about Tidal speakers I would love to try the Piano Diacera's in my system.

I would like the Metronome Kalista transport and the matching DAC.  I think I would be satisfied with that.
