Know anything about the BSG Technologies QOL?

Its a 1 Amp slow blow. The numbers are a bit confusing.

I know that the polarity of these things is critical. There is usually an arrow: does it point in or out? I remember having to fuss with this on my EMM Labs digital setup.

Preale, during testing of fuse I tried putting fuse in both ways and preferred the arrow pointing away from unit. This also was the way the arrow pointed in my ARC LS-27 and ARC D-450 amp after testing both ways. I would be curious to see if you concur.

I ordered the fuse this morning (small 3AG 250V 1 amp). When it arrives, and after a few days break in, I will report. Meanwhile the Qol keeps getting better. I now think that an excess of 200hrs. is minimum. Also, the use of XLR interconnects is essential. I don't know what speakers all of you are using, but this unit seems to work particularly well with electrostatics. I have it in the sound system that uses Sound Lab M-1 PX's.

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.
