What would you upgrade next ??


My system is finally sounding pretty good. Actually gives me goosebumps. But I'm always looking for the "weak link" in the system. I'd like opinions on what to upgrade next. I'm looking for retrieval of micro-details, air and space around each instrument and voice, 3D imaging, "palpability" of all the voices and instruments. Here is my system:
CDP: Arcam FMJ CD23T
Pre: ARC SP3c (complete upgrade/restoration at factory)
Pwr: ARC VT100 MkII (just re-tubed)
Spkrs: Acoustic Zen Adagio
Sub: Focal JM Labs SW900
Interconnect and Spkr Cables: Analysis Plus
Other: Speltz Autoformer set for 2X, use 8 ohms taps.

Thanks for your inputs.

Sugarbie;

I do have a TT. I didn't mention it because I wanted to know if the digital chain is optimized. But, since you brought it up, here it is:
TT: Linn LP12 (purchased new in 1977) w/ Lingo power supply & trampolin base
Arm: LOCI by Psionic corporation
Cartridge: Clearaudio Virtuoso Wood
Pre-pre: ARC PH3-SE (of course, the SP3c also has a built in phono stage)
Interested in your recommendations for upgrades to either the analog or digital chain.
thanks,

You have a decent CD player already. To really upgrade from there I would recommend you look at a separate DAC (a really good one).

Do you have a budget? Does the Arcam have a digital output?
Sugarbrie:
Yes, the ARCAM does have a digital output. Budget $1500 to $2000 for a DAC. Can I improve on the DAC that's in the Arcam ??
Thanks,
