I appreciate all the post here, No, I am not no sales man, I enjoy what I own, and in the end, that is what matters, I also enjoy audiogon, I like getting help from others, and like helping others, a fact here is I do not costantly do what they do on the HF thread,I try to talk about the Tara cables to others, and provide info from many sources, people can buy and prefer what they want too, just like I also enjoy the sound of classic Krell amp's like my modded Krell 700cx amp, my modded JBL L-7 speakers, have not modded the vincent cd-s7 player yet, was thinking about the Mullard 12ax7 10M tube, and the 12au7 mullard 10m tube, have not decided what to use for the power supply tube yet, tube's sound very good to me with Tara Labs cable's, I will say that the Tara Labs Cobalt power cord with oyaide termination's did a huge up-grade in sound for the vincent player, I use to have the Ayon cd-s2 player running direct to amp, that was lousy sounding compaired to the vincent that is half the cost, what do all of you think about the tubes I mentioned here?
