Converted a bedroom to be my music room. All 100yr old horsehair plaster walls with good insulation behind them. About R30 insulation above the ceiling. New carpeting. Audio rack and (3) record racks built by me and my woodworker son. Record collection stands at almost 900, which isn't much compared to some but I don't have but a handful which don't get played. I also had him make the 3 shelves for my audio rack, I machined the 12 tubes and the 6 captive/hidden leveling spikes.
These highly-regarded floor-standing speakers replaced the Reference 1 Meta that I had. The difference is crazy, now being able to pressurize the room at will with that "chest punch" that the previous speakers just couldn't do.
Luxman M-900U
Power amp that matches the C-900U pre-amp. Balanced (XLR) connections.
Luxman C-900U
Pre-amp, bought to replace L-509X integrated amp
Luxman EQ-500
Standard Luxman EQ-500 phono stage, fitted with up-level Gold Lion tubes though I got the stock JJ tubes with the purchase. It's heavenly, and both my turntables feed into it.
Luxman DA-06 DAC
Added this DAC also as used. It is SO much better than the Gustard DAC X16 that it replaced. Very happy with the analog sound and the soundstage it presents.
JL Audio e112-Gloss
Killer subwoofer x 2!
Luxman PD-171
A 2011-build belt drive turntable of exceptional quality, with upgraded Jelco TS-550S tonearm. Using primarily a Hana Umami Blue cartridge.
Luxman PD-121U
A 1975-1978 era Micro Seiki-built (to Luxman specs) direct drive TT with SME 3009-R tonearm. I use primarily a Hana ML cartridge.
Bluesound Vault 2
Streamer/music storage device. I have about 660 CD's ripped as FLAC (a few WAV) files. Digital Co-ax out to the DAC.
Nice set up! I am with you on soundstage and speaker placement. I am always surprised by how many audiophiles put their speakers too close together. No soundstage! I have never once experienced the dreaded "hole in the middle" that many audiophiles go on about. Congrats!
