Is it possible for any low signal tube to have it all?, likly not, It is probably like anything else, A balanceing act?, Grannyring, I enjoy your insight, and I follow your postings, what do you believe that will retain profound bass without looseing it in a tube cd-player, and that will improve the sound stage to come further in the room without being to forward sounding?, keep the bass and treble incredible that I have now, but improve the transparency and presatation of the sound stage?, the tube positions are 12AU7 and 12AX7, and 6Z4 recetifier tube?, any one may chime in please, thankyou to all.
