Hi, I'm interested in recommendations for tube amps for C1 Dynaudio speakers. The speakers are going in a 20' square 5.1 home theater w/ a Piega ribbon center speaker, mirage omnipolar rear speakers w/ a Denon 3803 receiver. A Sonos ZP90 feeds the denon from an adjacent wifi router, maybe a NAS later. All the other pieces can be changed if strongly recommended. My favorite sound was from quad 57's years ago but needed more slam. Ran some JC1's w/ Piega P10's and a wadia CDP years ago which didn't sound great. Didn't like "warm" speakers I heard in a hifi store years ago. Live in the boonies now w/ no place to listen to stuff. Would love to feed the amps directly somehow from the HT feed, and the SONOS as needed. Maybe a CDP too. Budget is 5Kish max? Almost bought a pass x250.5 but it was sold. If one can get 85% of a great sound for 50% of the price that'd be what I'm looking for. Thank you for any suggestions!
