I agree with the others regarding Coda. Even though you have a preference for tubes (I have also for most of my life), try to audition the Coda No 16 amplifier. I think in this very recent review, the reviewer nails it; the best of solid state coupled with the best of tubes (for the far less costly Coda CSiB integrated) without the heat and cost of ownership (tube replacement).
