Yes, I am familiar with them from the 90s. Bought 40 feet of the Apature Accuflow speaker wire and cut it down to 10’ runs to bi amp a pair of Snell Type J2s with a pair of B&K ST140s. The system was very good with one of the original Audible Illusions Modulus preamps, Phillips based CD used as a transport, PS Audio Dac, AREB101 turntable with my trusted Grace F9R and the system was great, listened to this set up for 18 years. Paid $1.00 a foot for the speaker wire. Enjoy the music
