The BEST system you've ever built !!!!

My best system so far is; Rowland consummate with phono(Preamp), Rowland model 6 monoblocks(amps), Aerial acoustics
model 8B internally wired with Audioquest kilimanjaro silver wire in Santos rosewood with stands(speakers),Audioquest Python balance interconnects, Audioquest Caldera bywired,looking to upgrade to Volcano.
EAD DSP-9000 MKIII balance(dac), EAD T-700(transport),Exact power 2000 (ac regeneration unit), Thorens table.
By far the best system I have put togheter and yes it AHHHH!!! audio nirvana.

There is a piano playing in my living room and it was brought to me by onkyo Dx-v787 and a pair of Klipsch SB2 speakers...now this is not my main system and I use it for home theater...(I have a subwoofer with this setup and another much more expensive system) the point is that I'll bet that if I listen hard enough, I can tell the brand of piano playing. If I put another $20,000 into my home theater... same piano. My problem starts when I begin to think that I can do better.

Rockport Serius II
Tenor 75wi
Aesthetix IO Signature with two power supplies
Audio Aero Capitole II
Talon Khorus X
Jena interconnects and cables
Dedicated 20 amp circuits with 100amp subpanel/ground

The system I'm building now:

Mark Levinson 390s player/processor
Tascam DA-P1 DAT recorder
Rega Planar3 table
Supex 900 Super cartridge
Monolthic PS-1/HC-1b phono stage
Mark Levinson 380 pre-amplifier
Mark Levinson 332 amplifier
AcousticZen balanced source ic
Transparent balanced ic to power amp
Transparent speaker cable
B&W 802 Matrix III speakers

Just got the 390 back (updated 39) and finally broken in.
The listening room isn't done yet, but my temp set-up is finally coming together. Need to add some room treatment, but otherwise a great setup for critical listening. Considering adding a pair of Martin Logan CLS electrostatics to alternate when I finish the room. The 802's throw a great image, but I miss my old pair of ML's.

Ear buds. I've listened to dozens of high-end systems and logged in thousands of hours on my own ever-evolving system. If you really want to hear what's on a CD, pop one into your computer or portable player and listen through ear buds. Their tiny transducers replay with startling beauty and accuracy the most minute subtleties in a recording in a way no combination of components can ever achieve. They simply have no obstacles to overcome in the way of room acoustics and mechanical compromises. You'd be shocked at the beauty of recordings heretofore relegated to the back shelf because of "harshness" or other shortcomings when played through earbuds. That said, I still tinker with my system and enjoy it immensely. But I propose that he who creates a system that can reveal "truth" of what's on a recording as well as earbuds do will have discovered the audiophile equivalent of the unified field theory. If you don't believe me, invest ten bucks on a modestly expensive set of earbuds and listen for yourself.
