My voyage into tubes started with a Tube CDP, i couldn't believe how much better it was than SS at that time (mid 80's). Then i bought a tube pre-amp. Now even my SS CDP sounded OK. Upgraded my tube CDP to Trans and DAC (late 80"s). Then i got new speakers, very revealing, now amps sucked. Bought tube amps. It finally came together in spades! Were i to start over today, i'd probably pin down a good neutral tube pre-amp and start from there to tune my system and room to get the sound i like to hear. Probably the last components i would buy would be the front end items.
