You never know what you're missing until you try...Different tubes do sound different, better or worse is up to your ears.
***Is It Me Or Have Todays Modern Tubes Gotten REALLY REALLY Good***
About 3 years ago it was the Quad VA-One EL-84 amp that won my ears & heart.Almost 3 years I ran that amp night and day and never felt the urge to roll any of the tubes,which I believe were E.H...A user interface problem forced it’s sale and now it is the magical Cayin CS-55a with factory KT88’s,AU7 & AX7 small signal tubes..Once again I find absolutely no reason to start rolling tubes.Maybe,maaayyybbbeee I could squeeze a drop more liquidity outta the upper mids and possibly a hint more shimmer on top but at what expense?I hate gambling.Anyone else noting the quality of today’s new issue tubes?
