Know anything about the BSG Technologies QOL?

Hi there, I just saw a local dealer advertising this on craigslist, They wont tell you anything about it except it works, it half sounds like snake oil and half sounds like it could be something.

They claim it is all analog and retrieves inner detail and has the "WOW FACTOR".

My guess after talking to the guy is is might be disgned around smoothing out microphone curves maybe? or sending out a ton of above 20KHZ info to do some pshycho acoustic/room type thing?

I'm just tripped out they wont tell you anything except, well set it up, if you like it awesome if not dont buy it.

I am genuinely intrigued to see if its truly real and if anyone has expreience. It would be nice to save a long drive to hear something or have something to look forward to on the drive.

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.

I concur with everything Pipedream says. My unit has been used over 600 hours, and it is finally smoothed out (I leave the unit on 24/7 and have used the Isotek burn in CD a few times over the period). One last thing: using the XLR output for the main channels also really helps, especially if the source-to preamp and preamp to amp connections are balanced. Since my whole front end is on an isolated platform, a setup like that improves the sound of any component. An added bonus is when you use a classic, analogue FM tuner like the McIntosh MR 78 or Marantz 10B tube tuner as a source. I am sure the result is euphonic, but addicting.

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.

Dear Pipedream,
Been reading our posts regarding the QOL. I have one on trial and have broken it in over 250hrs. I was just about to send it back today when I remembered your post regarding trying it after the source. I did that and it completely sounded much better than after the preamp. I am still not 100% for keeping it. It does change the sound for the better though. I ordered the Hi-fi supreme fuse for the unit. Haven't totally decided to keep unit. To me it sound so much better after the source. thanks Ron
