Tube amps under $7500

@porchlight1 @yoder  Thanks to this thread I am now an uncommonly well-informed tube amp shopper. Much appreciated.

@hickamore 

just had a thought:  what about bi-amping?  You could use SS on bass, and would give you more tube choices for treble.

@mdalton Interesting thought that had never occurred to me. I suppose it is a given that no tube amp in my price range can match its SS equivalent on bass? And if bi-amping with one SS device and another very different tube kit, wouldn't I then get into level controls and active crossovers? Remember, I am a lazy listener, not a gadget enthusiast.

definitely not expert in this area, but four different thoughts:  (1) some tube amps come with gain adjusters.  (2) if two amps have same gain, no issue.  (3) if different gain, you can lower gain on higher gain amp thru use of resistor on interconnect. (4) use an external passive preamp (attenuator) for the higher gain amp (For example, Lab12 sells one for $750.)  Again, just brainstorming with you, am sure others know much more about this, but if it works, you could save a bunch by getting a relatively cheap class d amp for lower end, and then you can splurge on a relatively low power tube amp for tonality at the high end.

I think that would only be true if your preference is strictly solid state for bass.  I had a tube amp that sounded great, but with steroetypical bass disadvantages.  My 24 WPC Air Tight has great bass control and plays very loud for my room and even with some previous 89 dB speakers.  For me many of the SS I would compare it to would play louder and have some more dynamic headroom that I don't need,  but would not sound as natural.  I think it comes down to what sound signature you're looking for and musical taste preferences to get the best match with you and your speakers, not necessarily a certain type of amp is "the best" at this or that.  You can go down a rabbit hole just in what is the best class D amp or if/ when is it better than A or A/B as far as what's best just for SS bass.
