PS ultimate outlet


So what's the verdict? A good thing?
gladstone
The 20a version is supposed to be less constrictive on larger amps. See PS audio site at AA site. I don't think it has been released yet, but should be soon.

I was wondering what the sentiment was about the 15 amp revised version, which I tried and was not bowled over by. The 20 amp version is quite different and includes an upgraded plugs.
I hesitate to enter the discussion, but here is my experience:

System: Arcam Alpha 8se, Silver Bullet 4.0, Wheatfield HA-1 (single-ended headphone/preamp, upgraded Mullard ECC82 and GE 7044 tubes), Silver Bulltet 4.0, Hafler P1000 amp (50W/ch solid state), DH Labs T14 speaker cable (6ft), Tannoy System 800 studio monitors (8" dual concentric, 92db sensitivity). The UO15 was used for the power to the CD player and preamp only (one on each outlet).

Source: "In a Distant Place" featuring Nakai (American Indian flute), Eaton (clef guitar), Clipman (percussion), and Nawang (Tibetan flute)

At first some of the tube magic seemed to be gone. Some might call it "air." The highs were tame, the mids and bass more prominent. But as I continued to listen I could hear the resonance of the guitar strings and even the beats created by adjacent strings being very slightly out of tune. I could hear the string sound as it decayed naturally and longer than I had ever heard (still beating). This decay into silence was also true for the flutes and percussion. What seemed to be at first a change in balance away from the tube magic, was I believe, a change to a better balance without artifacts (yes I believe artifacts can be pleasant in high end stereo). I listened to the entire CD without the slightest fatigue from the flutes, which I have found hard to come by with Tannoy studio monitors. Their frequency response is stated as 47Hz-20kHz. In the past, I have always felt that they were far short of the 47Hz bottom. With the UO15 in place, I'm convinced that they do extend as low as advertized. (Once again, balance across the frequency spectrum appears to have a big influence on whether this speaker sounds like the studio monitor it is supposed to be).

My experience causes me to highly recommend this unit. I'll certainly be keeping mine. However, be prepared for an initial shock. Whether you believe the change to be for the better or not will depend upon both your system and your ears. Its worth trying.
dekay, if steve bruzonsky still has any vans evers unlimiters left, (adwertized here on a-gon), i tink yule be wery happy w/them for only $325. i bought two for my amps, but w/only one in use, i got *no* restriction in dynamics from my two electrocompaniets driving my monitirs, & from my two bridged adcoms driving my subs. actually, a small improvement when using the unlimiter - everyting seemed to get yust that much tighter & quicker - & i was only hoping for no degradation! ;~) so, i am using the other one on my source components... ;~)

Thanks Doug: The Vans was the other one on my hit list. I am really just looking for an extension cord with surge protection that will not mess with the sound. Seems simple, but it's not.
