Cheap, get your toes wet option: used Onix SP-3 (about $400)
Midrange option: Prima Luna Prologue One or Two (about $1k )
Highend option: Cayin A88-T (designed to sound like McIntosh 275) ($2k ).
All three have received glowing reviews in the magazines. I own all three and can vouch for them. The Primaluna has autobiasing which makes it easy to use and easy to try different tubes with.
