I see Lions paraphenalia? Are you in Detroit? I'd like to hear that QOL unit in action.

I read a review of the BSG Technologies QOL in the February 2012 issue of The Absolute Sound. It was an interesting review. I hope to try one of these in the near future. Your review is similar to that of Robert Harley’s. I hope to listen to the effects of this item in the future. It is not inexpensive, $4000, but if it does what it claims to do, I’m willing to save up for it.
Thanks for the review of this item.
I had a recent experience with the QOL for several days in my triamped system (Magneplanar MG20's plus Hsu tower subs, tube electronics, VPI Classic, C-J cd player). I really didn't want to like it, but that didn't quite pan out.
I agree with most of Ozzy's conclusions, but might add:
1--defeating the circuitry with the bypass sounds murky compared to taking the thing out of the system entirely, so A-B comparisons go way in favor of qol.
2--Simply put, my system never sounded as good. Major improvements in spatiality, dynamics, fine detail, and liquidity were not subtle. The bass (a fetish of mine) became focused and the pitch much more precise. Voices "floated" with an ethereal, almost ghostly, quality that was quite sexy. The image size was MUCH larger, and I could definitely hear material coming from in BACK of me--a first. The stage goes WAY past the lateral borders of the speakers, even more so than usual.
3--There is a qualitative difference that is tricky to characterize. The music made me "happy" in a way that has become rarer as I have become older. It's as if endorphins have been triggered and the musical pleasure centers energized. It feels really, really good. I can't guarantee that this will happen to you, but my friend who lent me the unit knows exactly what this is about.
4--If your musical experience is 30% better with qol, your system need only cost $13K for the admittedly high price of 4K to be justified.
Who knows what the future will be for this circuitry or for BSG? There's no doubt they could sell more at a lower price point. The unit is way overbuilt, with balanced AND single ended inputs numbering 4 and outputs 2. Add a volume control, and it's a preamp, but make it simpler and the price could go down. Will licensing agreements materialize for this company? Will a competing technology become available for hundreds rather than thousands? I'm not sure I can afford to wait for these questions to be answereed. I'm on the verge of ordering one
My review on the QOL stage was just put up on the website hometheaterreview.com were I came to a completely different opinion then yours about the performance of this device. It pretty much did nothing postive in my system and I gave it every chance I could to produce just a little magic and it was not happening. Frankly, I can't see why anyone would lay out 4K for this do nothing device.
Teajay, I just read your review. There MUST be something wrong in the unit you had or there is something quite unique with your system (good or bad).
You should have heard a huge difference.
It is a huge improvement in my audio enjoyment.
True $4000 is a lot of money for the Qol, but many of us spend that on speaker cables. And to me, there has never been this much improvment with any cable change I have made.
And for that matter any Preamp or CD Player upgrade either.
You also could claim I'm deaf if you want, however two other experienced listeners in two different very good systems had the same experience I did. What I did not put in my review is what I consider the most bogus aspect of the SCS, that when it is engaged it increases volume from anywere from 2db to 4db depending on the recording which any seasoned audiophile knows will either at first either sound different/better compared to a lower volume. If you match the volume between the bypass and the active circuit you hear no difference at all. When this was mentioned in another review BSG Technologies suggested leaving it the active mode, not going back and forth to compare, because the active stage really was not raising volume, but giving more information that is experienced as an increase db.Please give me a break! If you like what it does in your system that's the most important thing, and yes anyone can try it for 30 days at no risk. I personally would not use it in my system.
