over things like Walker Velocitor, Audiomagic, etc, etc. Interesting read at least, so check it out.All I can say is, it must be several order of magnitude better to warrant such claims compared to their older products, such as BPT-1 signature. I used to have that unit, which was nice but nowhere approaching the "best."
Follow Ups:
Although I had not read that review until now.This unit contains a variety of technologies, some well-documented, some more on the fringe. But the results literally speak for themselves. Despite my well-prepared expectations, the benefits of this unit still surprise me a bit.
I was going to wait until I could take better measure of the unit to write about it, perhaps in comparison with some other brands, and perhaps in conjunction with some industry standard test methods. But, I will say that it does amazing things. I'm not prone to hyperbole. But...
I put the BP-3.5 in my system, and burn it in for a couple of days. I did this before trying to assess any differences. Then, I simply noticed what drew my attention. Details now take on musical and auditory meaning. Audiophiles often write "I heard details I had missed before," that this applies here. But it seems clear why this is so. Sure, I had heard parts of those sounds before; but now they appear with more of their subtle aspects intact, those aspects that trigger the illusion of it being a live sound. So, my nervous system snaps to attention. I take note of as a distinct, integral sound in space for the first time, even though I'd heard most of the component sounds before. You don't have to look for it; it grabs you.
It is more clear what instrument or playing technique resulted in a sound, as well as why it was placed there, musically. Some choices of arrangement or production, especially of dense material, make musical sense for the first time (try to untangle the LF instruments and samples used in Peter Gabriel's Up, an album which comes across muddy and dense on most systems). Mutters and mumbles from vocalists; noises in the middle of an orchestra; nearly-subliminal backing instruments... these jump out and alert the auditory system more as live sounds do. I am clearly hearing more of what went into the recording. Dozens of aspects come into focus and make sense in auditory and musical context. Not so much need to close your eyes. It's unmistakable.
Interestingly, the overall tonal balance of the system is not largely changed on first listen. It is the subtleties that have changed. Virtually all high-end virtues come alive, improved by the BP-3.5 in the system. A midbass fullness, presumed to be a characteristic of my tube amps, flattened out. Bass extension deepened. Same for a mid-treble peak, which smoothed out, revealing a more-extended yet more-subtle upper treble.
After a week, I received by mail a slightly longer AC cable for the unit, one that could reach my wall outlet without using an extension. (I had been using a 3-foot, 10-gauge extension for a week.) I also received another BPT power cable, this time for the Sony SCD-XA777ES SACD player. These changes brought further improvements, most noticeably in the bass. Like going from a tube amp to a solid state amp, the bass transients are now faster and more controlled. The sense of size and space in the lower frequencies is enhanced. Sharper attacks are heard from bass and drum. Bass notes and shudders seem to go right down to bedrock, instead of sounding as if on a resonant wooden stage.
This isn't one of those mods that simply sounds different, which some listeners declare "better," and others, "worse." The sound is clearly more true in virtually all respects. In a couple of cases where I felt the BP-3.5 was doing something undesirable to the sound, I later found it was simply a revealed flaw in the system, now unmasked (to use a psychoacoustics term).
Instrumental images are far more focused and better separated from each other. Most images are moved rearward, away from the speakers (distortion tends to draw images toward the speakers). Treble images are located as deeply as the lower frequencies from the same instruments, no longer thrust a bit forward. Harsh passages or instruments (like a hard cymbal hit) that seemd to be overloading something are now shown to be more true. Voice texture, as in Mark Knopfler's You and Your Friend (from On Every Street) is revealed to have a rich mix of natural smoothness and expressive growls, enough to make me laugh aloud.
I find myself playing the system at higher volume settings, because there is less of the stress that says "too loud." I didn't know my amps had that much headroom.
It is now easier to hear tweaks (feet, cables, VTA, etc) or problems (too much Caig left on a connector; lint on a stylus). Yet, the system is more forgiving. Objectionable harshness and muddiness is reduced, so everything sounds better.
This is the opposite of the common audiophile phrase "ruthlessly revealing." The BP-3.5 helps make all recordings sound more true... many recordings are better that I gave credit. (I have found that phrase "ruthlessly revealing" to be a "tell" of a bright or harsh component, one which the reviewer likes and thus excuses. Same for the term "fast." )
Recordings sound more different from each other, yet clearly closer to what went in the microphones. This is hard to prove or even express. Our highly-evolved nervous systems just "know" when a more realistic sound is presented... not to mention dozens of them at once.
The degree of improvements from the BP-3.5 is significant enough that you will have to rethink your upgrade priorities, if not your perceptions. You will change your conception of your system's virtues and vices. The improved purity and natural musicality of a CD or SACD front end, for example, may lead you to desire less euphonic filtering in downstream cables and amplification. You may choose more neutral cables. You may try again certain tubes, previously dismissed as a bit ruthless or even harsh. If triode mode sounded too boring before, you may now find that it sounds more true to the source, while ultralinear mode is shown to be a bit forward and artifically exciting. You will find yourself re-evaluating what your favorite recordings sound like. You will feel as if your listening skills have improved; it is like finally getting the right prescription of eye glasses.

Jim - Could you tell us what other conditioners you've used in your system? Thanks.
I had been using an older Straight Wire Power Purifier PP-8 for front-end equipment, nothing for amps.
At the time I bought it, I don't think the Signature Ultra existed but mine has all of the silver wiring, the bybee devices, silver 20A power cord, the special capacitors but alas no cryo treatment...It is WAY bette than my Righard Gray 400 or my previous el cheapo balanced power unit. I can unequivacably say (without having any other high end power units to compare it to) it's Great! It does also help the video.

Written in Srajan's typically dazzling style, chock full of challenging words and clever references. But have we done our homework? Examine this quote:Next you'd have noticed dynamic peaks. They were farther above the median loudness of each song, in actual dB. This increase of dynamic scope was accompanied by an uncanny realization: These gains were not restricted to certain sections of the audible range but occurred, in one giant and powerful sweep, across the whole nine audible yards (it takes 9 yards of fabric to complete a gentleman's three-piece suit, did you know?).
The origin of the phrase "the whole nine yards" is subject to much conjecture. There does not appear to be any evidence of this appearing in print prior to 1967, so it's likely that this Americanism was invented in the '60s. Cement trucks, nun's habits, sails, gentlemen's suits, and machine-gun belts all get a whirl. None are proven.
I think we do know, however, that it does not take 9 square yards of fabric to complete a gentleman's three-piece suit.
A fun article.

that's some useful history info, but does anyone have any thoughts/experience regarding the reviewed product?Could it be that I missed the whole magic by mistake and mistakenly sold my BP1 signature? My modified battery-based power generator did sound MUCH better at the time...
I followed your link and read the review. I've not played with power conditioners in my system, so the only things I could relate to were of a literary nature! Hey, at least you know I read it.

That caught my eye in the review, where the manufacturer mentions using DC power with a battery-operated generator.Who makes such things? What was your's?
I'm very curious about the 3.5 as well, I was hoping someone might step up to the plate (the origins of that phrase not being in need of illumination, I hope;-)).
If you are good with electronics, you can certainly make a AC-DC-AC conversion contraption, using batteries and conversion circuits.Me, not being so astute, opted to use a XS technology Strata 1000 unit (company is defunct now), which is basically an expensive Battery-based UPS. It's not a cheap UPS that chops up sine waves, but creates "perfect sine wave" from the battery-buffer. This unit was good stock, but had some issues. Internal wire/solder quality as well as AC outlet quality was FAR from ideal, not to mention cheap captive AC cord. Expected result was somewhat laid-back sound with restricted dynamics. BUT, the rest of the sound was so pure, I had to mod it. I changed wires inside with some teflon/silver, Belden 83802 wire, put on some ACME silver-cryo outlets, and installed a male IEC jack to use good power cords with the unit.
Now I love this unit. Unfortunately, it can't be bought anymore, but there are people who still make something similar, such as PowerWare...
"the whole nine yards" comes from the use of Gatling guns a ways back. The "belt" of bullets was nine yards long and if the situation called for it, they would need to use the "whole nine yards" to fend off whomever was on attack.

Check out any Civil War site. Here's one.

I've heard that too, but it was for machine guns in world war II, I think on B-52s. Again, 9-yard gunbelts. (But that was the History Channel, and I've seen them make stuff out of thin air before) ;-) But according to Metrallas link, the gunbelts didn't actually reach 27 feet in length. The one for yards on sailing vessels looks like a good one. Sounds like a sailor, "argh, we'll give 'em the whole 9 yards, blackbeard".Here's an idea. People had not yet learned to count in more than single digits, so 9 was the biggest number they could come up with. "Duh, we used the, ummmmm, whole 9 yards". hehehe
And which sounds more like a "baker's dozen". It's not 11 or 13, as some would say. It's however many came out of the mix when aiming to make 12.
