What would you upgrade next ??

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,
Mabonn

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,
MABonn

Wow !! Thanks everyone for all your responses.
Sugarbrie, I have not done anything wrt AC power cables, conditioning, separating analog and digital (AC). Any cost effective suggestions would be appreciated.
Jaybo: What would you recommend for a speaker upgrade that would be cost effective ? Note, I traded a pair of Innersound Eros Mk II (active) for the Adagio's. Just couldn't live with the beamy radiation pattern of the Eros.
I agree that I need to work on room treatments.

I am truly amazed by the responses this thread has generated. The question is, "if my system gives my goosebumps, why change it ?" My experience has been that you won't know the detail you are missing if you have never heard it. Like trading up from a Nikon to a Leica or a Hasselblad. If you have never seen a photo taken with the better optics, you might think the detail presented by the Nikon is "all there is". Can I improve the resolving power of my system ? If so, what upgrade would give me the best "bang for the buck" ?

Thanks again for all your responses. Here is my reaction to your comments so far:
Some say start at the front end, either a better CDP or an outboard DAC, followed by pre-amp. Audiofeil says no, upgrade the speakers. Say I can get $2500 for my Adagio's and kick in another $2k. Audiofeil, what would you recommend used for ~$4.5K that you think would best the Adagios ?
Others suggest room treatments (no doubt a good suggestion), AC power conditioning, power cords, and isolating the CDP from the AC to the other components. What specific recommendations would anyone recommend for AC conditioning, power cords, and isolating the CDP ??
Dave b suggests adding AV123 supertweeters. I am really intrigued by this suggestion. The Adagios have circular ribbon tweeters that are supposedly flat to 30KHz, and I am 56 yrs old. I think my hearing is pretty good, but I'd be surprized if I can hear beyond 16K. I'd like to hear more from you as to why you think adding a tweeter that extends thehf response from 30K to 50K would add to my listening experience ? The reason I ask is that this upgrade is relatively inexpensive, so it is certainly worth considering.
