Anyone HEARD the qol 'signal completion' device?

Douglas_schroeder, is your post based upon actual use with the "qol", or on preconceived philosophy re: all optional devices in the audio chain?

Not to get too far off topic but I was struck by a comment Douglas made above. Your ears must be hearing some way different stuff than mine when it comes to networked cables. My experience is with MIT stuff so can't really comment on others but I've had the exact opposite result in that they present absolute resolution and clarity, not sacrifice it. As a matter of fact, I recently changed cables and it was the biggest upgrade I have experienced in 30+ years...mostly resolution and clarity along with dynamics, imagine and all that goes with.

I don't have any personal experience with the qol and not too much interest. My only exposure is a very good friend who had one on demo and returned it preferring his system (quite a fine one) without.

I'll offer my opinion as well but may be a little off topic. I was a MIT user for 14 years and decided to do some practical experimenting after numerous music lover said that these cables were choking my system. So, I took them up on their offer and was blown away with the results in my system. Sure MIT has a jump factor in soundstage and imaging but to me that's it, I found low level detail, shading and ambiance to sound artificial. After spending 8 years in England, most of the audiophiles I met there described MIT sound as "Hi-Fi-ish" and unnatural sounding.

Unsound makes a good point. Has Doug even heard the device in question?

I conducted my assessment of QOL in my own room with multiple systems.
