Know anything about the BSG Technologies QOL?

Preale, I agree, all equipment including qol need to burn in to get optimum sound reproduction. I just think the burn in is a small factor with the qol unit compared to speaker and system adjustment. Right out of the box the qol was positive and only got better. What has surprised me is how some units and cables absolutely make your ears hurt and can take 200 to 600+ hrs. to come on song. The Shunyata Triton and their cables take 200 hrs to sound good with more to come. The ARC preamp and amp took 200+hrs.to sound fair and 600+ to come on song. When listening to all these early, before burn in, hurt my ears and made me question my purchases. I almost traded amp as it took the longest, but time transformed the sound in ways I had never experienced or expected. That to me is burn in that is extremely relative and can effect whether you want to purchase something or not. With the qol I liked right away then started falling in love.

Without a doubt, the Hi Fi tuning fuse is worth the money. I had some delay, because I ordered the wrong size. It seems to smooth out the sound and remove a small amount of grit.

Preale, I have the regular version of the HIFI Tuning fuse in mine. I'm going to get a Supreme.

Oddiophool, the 6 moons review was poorly written, I couldn’t tell if they liked it or not.
Suffice to say I find all their reviews too flowery with little substance. The Qol needs to be listened with the volume left alone instead of constantly fiddling with it like they did in the review. The dynamics is one of its main virtues.
Plus they tried it in so many systems with so many different listeners. Terrible way to do an analyis.

I just read the review, which taught me more about frying eggs than anything else. Something alluded to in a letter in this month's Absolute Sound indicates that there is an increase in forwardness of the image. In my system (Sound Lab M-1 PX electrostats) the Qol seems to stabilize the image in speakers that often sound too recessed under normal circumstances. In the 6 moons article manufacturers reply, Larry Kay is correct when he states that the variability is in the recordings. We all have noticed the annoying lack of consistency in R-L balance in any number of recordings, just to name one issue. I agree with Oddiophool: put the Qol in one system and live with it. After about two months with the unit I have found that, in general, it makes the sound more cohesive with little or no loss of transparency. I would like to have heard a comparison of the effect of Qol on the Duntech Sovereigns vs. the Beveridge electrostats.
