Quality PC: plug into wall socket or conditioner??

Jeb.

Actually, my upstairs neighbor was not exactly threatening me. He likes the "Who", and especially the album "Who's Next" Nevertheless, after a few beers, and laughing over how bad the Cubs and Phillies played last season, he chilled out.

However, whether it was audacity, balls, or neurosis. I involved him in the speaker cable merry-go-round listening session. and which sounded best on the (now) 7th play of 'Won't Get Fooled Again" Was it cable #1 (a dealer loaner Audience 24e) or cable #2, Nordost Frey speaker cables( also a local dealer loaner). He both liked selection #2 a tad better. When I mentioned the approx. retail price of each cable, he explained he could probably buy three new shotguns and a replica of Jim Bowie knife.

Now, I know I am going to get schooled on shotguns technology, hunting knives,and survival techniques.. However, he is a good guy.... I just hope he likes Lou Reed, inspired album, "Rock and Roll Animal"

JL135, I will let you know about the power line experiment, and not about how well I can hit a skeet at 50 yards.

I plugged the Acoustic Zen Tsumani PC directly into the wall socket, NEXT to the power line condition PC. There seems to be a marginal improvement in the sound. The remaining PC's are plugged into the power line conditioner

One unknown factor is: I switched IC's from the Rega CDP to the integrated amp. I am trying out the Nordost Red Dawn Flatwire a previous generation IC against the Morrow MAP3 which previously ran from an outboarded phono preamp, the Musical Surrounding Phenomena II which was sold as part of Project Downsize. However, the Morrow was adequate for that task, but not serving as a CDP IC. Interestingly, the Nordost has more inner detail, and better dynamics but the upper highs are somewhat congested Cursed trade-offs!!!

Both replaced a Chord "Chameleon" recommended by Rega for the Apollo CDP, and yes it did sound better when I first plugged it in 3 years ago. It is more balanced across the board. The question arises is finding a much better IC for the Apollo., like putting a Ferrari engine in a VW bug. Somewhere in the sound transfer, the law of diminishing returns becomes one of finished, caput returns.

However,the Nordost and Morrow Audio ICs will be sold and came out of my prize possession of old dog IC's. For example, the Synergistic Research Alpha Sterling, Monster Cable Reference( vintage 1988), MIT budget IC which is a dog, an Audioquest Cobra ( under $50) and lastly an Audio Magic Spellcaster II which was my major IC for years, and served multi-purposes. Bright and somewhat edgy, it is very detailed and possess explosive dynamics. However, its connectors need a DETOX cleaning because you got to screw the connector shell to tighten the connection. This IC according to Audio Magic was $700.00 (vintage 1991).I paid less than half via a rep's misquote

However, and this is the problem with the IC merry go round, they get outperformed, or become obsolete over (a short)time period. Whereas in my experience, speaker cable seems to have a "longer shelf life" in terms of delivering respectable, competitive sound.

Maybe because you listen more closely in evaluating new speaker cable and the improvements check list is multi-faceted: better bass, smoother highs, transient speed, and a few other areas related to overall speaker performance, including the elusive quality of musicality....that is, does it draw in the listener; hold their attention; offer a mesmerizing euphonia; or deliver that much over used phrase....it sounds like "real" music, or "natural" sound, or gets you "closer to the source".

Sunnyjim - I find the sole largest indicator of plugging direct into wall or not is (1) the quality of my line conditioner and (2) the quality of my house wiring. My home was built in 1990 so wiring fairly new and I have no issues going direct to wall on my amps, and they actually sound better (or at least I convinced myself of this). I have lived in older apartment buildings in NYC and amps direct to walls their did not sound better (different amps but much poorer AC distribution). It is all trial & error. The key is these forums...using someone else's trials...

If one plugs directly into AC wall outlet there is still the opportunity to keep adverse effect of noise or interference within the house wiring from affecting the component directly plugged in.

Different vendors sell items to passively diminish noise and whatever interference is preventing system clarity by plugging such an item into an unused outlet in the same circuit.
The least expensive one which worked for me is the Flying Saucer (from Machina Dynamica) for AC wall outlet. With some of these inserted in unused outlets their cumulative effect can be startlingly effective in letting us hear just how much better things can sound without changing components.
A cheap and simple step toward optimizing your system performance.
