What Combinations of Components Have You Put Together That Sound Good?

Verging on vintage- A highly modified Rotel RCD 991 (Burson discrete Op Amp replacements, Dexa clock, higher grade audio caps in signal path, etc by Parts Connexion, Canada) to ARC Ref 3 to modified McCormack DNA 1 (SMc Platinum Ultra with Plitron transformer etc.) driving Thiel CS 3.6 speakers. Running dedicated AC line to AQ Niagara 1000 with Shunyata Alpha HC power cables and AQ Columbia XLR interconnects. Characteristics of this system are low noise floor and good dynamics with nice soundstage and good frequency balance. Pieces work in harmony having good impedance match between
pre and amp and amp is able to fill heavy current requirements of Thiels. Purchased every piece used over many years on a teacher paycheck. It would seem that the CD player is the weakest performer, but I have tried others that cost 2X or 3X without any great improvement. Hoping to score a used Hegel Mohican to compare in the future.   

No subs with the KK III's Doug?

helomech - was unaware of the  Stirling Broadcast SB-88s. I do know some Spendors can be auditioned locally though.

jred - LTA sure comes up a lot as a big positive!

asvjerry :-)

richopp - gotta hear myself some of those Magnepans, I think there is a dealer somewhere in Seattle. Which model are you currently running and do you use subs?

yabe1951 - ah vintage, I truly miss my AR 9 speakers, coupled with my Carver C500 power & C4000 pre amps, my Oracle turntable and Teac tape deck, all channeled through my SAE graphic equalizer!

For reviews of products I always start sans subs, then after adequate experience with the product, I roll in the subs.

Sennheiser HD800 with Moon 230 HAD preamp DAC

MAC MHA 100 (50 W headphone amp), PS Audio Direct Stream DAC w/ Bridge II, Fostex th900 MK2 w/ upgraded silver/copper cable and titanium connectors. Wireworld gold XLR and Transparent ethernet cable. Obviously a headphone/ streamer set up and will blow your ear drums out before it ever hints distortion. I have a pair of Solilouy 5.1 speakers that match well and doesn’t beg power from the MHA 100. Open back headphones would elevate this system to next level, but i require the quiet provided by closed cans. Whole system cost me about $11K new and used gear (retail= approx. $14K. NO REGRETS. Once the cans go on, i’m in my own world of audio bliss.
