Know anything about the BSG Technologies QOL?

To Cobra: loudness in live music is a mysterious thing. e.g. The loudest a solo violin can play is about .02 acoustic watts. A bass drum could pump out 20. That is roughly 1000 time louder, yet ,subjectively both can compete because subjective loudness involves other things. I am sorry about quoting those prices, but for a well-heeled audiophile who will spend $4000 on a pair of interconnects, the additional expense for Qol would not amount to much (and, he/she can always return it). Long ago, before I started producing pro CD's, I gave up the idea of reproducing the actual live event. I was (and am) satisfied to put things back into the recorded event that have similar parameters. Even if we could reproduce the actual live sound, we don't have the physical presence of the musicians, 50% of that performer-audience relationship that often propels great performances in concerts.

Well, no foolin'. Sure perception in sound is different from emprirical performance. But loudness doesn't come free. If all other things are equal or consistent and one pre-amplification stage change is made, and it results in more dynamics or gain yet there is no change in amplifier output, something is amiss in the credit chain of this equation.

Most concert recordings are woefully short of the live listening experience, but occasionally, enough is captured and re-presented well enough to be a credible facsimile. When that happens I'm happy to hear it. But exaggeration isn't welcome..

Sure, the customer who spends $4K on interconnects will find the QOL's expense also incidental. I have two systems for which their cost dwarfs the expense of the Qol, but still, even if I'm in the mythical 1 or 2%, that doesn't mean I think it's a good thing for the industry at large to pin its business on more of me. Selling a metal box as a mystery rather than forthrightly outlining its operation benefits very few. In software, we have an axiom that patents and stealth are worth next to nothing. Your job in a technical innovation is to put it out there and then run faster in terms of technical iteration, than everyone coming after you. So you may as well explain yourself, clearly. Either you're serious about innovation as a treadmill mandate or you're not. When a company obfuscates its working methods as opaquely as QOL, I have to take the default assumption they are not serious about genuine innovation until I see otherwise.

But that's the minor point. For anyone who owns it, I want to know whether it gets them closer to a perception of musical realism or not. A huge soundstage characterization tells me nothing about the QOL's contribution to fidelity if the soundstage is huge whether that's the right presentation or not.

Phil,

As a technical person myself, I had many of the same thoughts and reservations you seem to have. I am not one for mystery but rather facts. I then did myself a favor and approached BSGT for an audition. Fact...I loved it and it did what it was supposed to do without diminishing the fidelity of the music. As a signal purist, this was extremely important to me.

I liked it so much that I immediately became a dealer and added it to my line of wonderful brands of gear and our line of custom music servers.

I have said this in a previous post and will say it again. I don't think BSGT is going to give their secret sauce to anyone, anytime soon. That said, do yourself a favor and have a listen. You may just be pleasantly surprised and inspired to listen to your entire music collection with Qol to hear what you have been missing all these years.

Ozzy, I am happy to hear you are loving the unit. That comment has not even started to get old to my ears.

If you or anyone is in the San Francisco Bay Area, I would be happy to audition a unit for you, at our shop or at your home. Just give us a call... setonav.com 510-279-2600

I don't think that the soundstage is larger than life. The way I would characterize it would be to say the there is the illusion of more air around the instruments. What I am evaluating are commercial CD recordings that I actually made myself. Since the BSG unit is so new, the one thing nobody can talk about yet is the synergy between it and other components, particularly loudspeakers. I suspect that really analytical transducers, like planars and electrostatics really benefit from this technology; while big box monsters, like the Wilson Alexandrias might not fare so well. All the controversy made stem from the synergy issue. After all, everybody knows about this problem in matching the right amplifier with the loudspeaker. That is why BSG offers the 30-day money back guarantee.

Phil, My answer to your question is yes.

By the way, I at one time owned the top of Zu's cable. Today, I use a simple 5N Pure soft annealed silver cable at a fraction of the Zu cable cost.
Again, to my ears, my system, my tastes I think it sounds better.
Don't get mad or upset, go listen for yourself to a Qol.
