Know anything about the BSG Technologies QOL?

I certainly do. For us it is all it has been described as. Our system never sounded closer to the live event. No loss of transparency that we can detect.
Instaled between pre and Amp. The Qol reqiured over 300 hours to sound its best. No fuses yet, just a Triode Wire Labs AC cord did the trick.
Now you gents that have not heard one in YOUR system get over the marketing nonsense and prose. Gets one interested, that is the whole idea. Next would be demo one. Then and then only make up your mind. really that simple.
In all fairness to any Manf listening is the only way to tell. One may feel that the marketing prose is a bit much or the claims made difficult to believe. Howeve boys proof is in da pudding.
I would more than happy to demo the Qol in anyones home in the NY tri State area.
now what we heard. A more realistic sized soundstage. not overblown, but larger. height of soundstage was really exposed. Tonality did not change for the worse, actually improved. Soundstage came forward and deeper with greated width as well. No loss of clarity when in. the bypass swith is moot really. no need for it. Once Qol is engaged unless you play a worn or scratched LP just no need.
As far as tweeking goes a Triode Wire Lab 8ga PC worked well for us. Have not tried fuse . Running single ended connection not balanced. Tried balanced in other systems and feel there may be an advantage in sonics bt jury is still out.
As an aside so far every buddy whom has heard this in their system bought one.
Really what do have to lose, try one. My bet it is a keeper. Until then chill.

Almost forgot. The balance thing is recording dependant. A balance control really helps out. Or sometimes if one uses tubes that one is stronger than the other which adds to the inferior recording.
As far as fowardness is concerned, depends on recording as well.
Living with Qol now for over 8 months and hearing it numerous systems, all I can say is it is not going anywhere. One would have to rip it out of my dead cold hands.

BTW guys where do you have the Qol installed ? Before or after the Preamp. In our situation it is after the preamp since we use a Phono/pre combo.
At first qol was to be installed before the Preamp, then an addendum was issued by BSG suggesting after the preamp.
BTW it likes footers as well. Using ebony cones with great affect. So experiment away dear chaps and always have fun doing so.

Ok here are our findings about Qol. It takes 500 hours to sound its best. That is when we detected so more changing of sound. Around 500 not exactly. Powercords do make a difference as well as power correction devices[ Uberbuss ].
Footers too contribute to more focused bass and tighter images. not to say as is is bad, just that with better.
We have tried, Ebony cones, Soundfusion, Pon -tunes, Ayre wood blocks and brass cones so far [ we like the Ayre blocks ]. All different results. realy is system dependant. Basically a tone control footer wise.
Let ya know how the "supreme" HIFI Tuning fuse works out for us. last but not least , leave it on 24/7 makes a difference.

Hey guys if you are using the Qol after the preamp, please try after source instead. Since I do not have a dedicated phonostage we placed the Qol after the preamp.
A buddy brought over his phonostage so we decided to listen both ways. We really liked the presentaion after the source.
I will keep our findings secret until you try and tell us what you hear.
Received the fuse a HiFI Tuning supreme. Expensive little sucker, but man O man it does make a difference for the good.
Balanced if you can will also add to the pleasure. also if you have the original version before the top cover change, dampen the top cover inside with either 3M sheets or dynamat.
Have fun trying and report back.

Sorry to hear of your misfortune. However it is damaged goods.
You did agree to the terms when purchased. BSG has every right to deny a return. As a new company though perception is the key. I have mixed feelings about this.

Bought the small Hifi Tuning Supreme fuse. It does not fit. Bummer. Is it the fuse at the IEC ?? Mine is a standard size. Is there another inside the Qol ??

Thanks Preale. OK my bad need to buy large size.
