For anyone who moved from tubes to solid state — a question

I'm the happy owner of a fairly new tube preamp and monoblock amps. I love it and have bought new tubes. To have another option for warmer weather or possibly a second listening room, I got a very good solid state integrated. I've run the tube preamp with the solid state amp and it sounds quite nice. I love all tubes, too.

But this question is for you. Please forget the convenience factor for a moment, including the issue of tube replacement etc. Also, forget about those cases where you bought new speakers and needed more power, etc.

Assuming you had quality tube gear with sufficient power — here's the question if you abandoned tubes for SONIC reasons:

What what is that tubes couldn't give you?
What did your solid state gear do for you which was so much better that you divorced to marry anew?

I'm curious about what people list as the positive sonic reasons they love solid state (including A, AB, D, etc.).

Thanks.

I don't use valve power amp below 300, only SS. 300 and above is Valve

Not sure I understand. You don't use valves/tubes *below* 300 wpc? Only *above* 300 wpc is valves/tubes? I would have thought it was the opposite.

In my experience it’s all about matching the amp and speakers. When I was running Spendor D7’s and moved from a Cary tube amp to a Pass XA30.8 SS amp (with actually less watts) I realized a substantially better bass foundation, articulation, and slam.

I later made a speaker change to Devore O/96’s which are exceptionally easily to drive. I acquired a Line Magnetic 805ia SET tube amp to try with the O/96’s and the sonic improvement was astounding compared to the Pass, including the bass, as well an overall rich sound with incredible detail and beautiful nuance.

So I don’t think bright lines can always be applied comparing SS to tube amps - it’s about component matching.

^^ This!
If your speaker is of reasonable impedance in the bass (8 ohms or higher) then its no worries making bass. Some tube amps (like SETs) do have trouble making bass impact due to phase shift in the lower octave. But if the amp has the bandwidth to prevent that then bass impact is no worries.

Many solid state amps actually overdamp the loudspeaker, as amplifier technology in terms of acting as a voltage source has far outstripped loudspeaker technology in this regard- no speaker ever made needs more than 20:1 damping factor, yet there have been solid state amps with damping factors of 1000:1. Overdamped speakers tend to have a coloration often called 'tight bass'; no such thing seems to exist in real life. But audiophiles often point to tight bass as a good thing, even though its pretty obvious its an artifact and not neutral.

There are a few good hybrid power amplifiers out there.

I always learn from your posts! As I mention to three_easy below, I'm hoping for folks to compare:

well matched amplification and speaker -- with TUBES
vs.
well matched amplification and speaker -- with SOLID STATE

If other factors are responsible for a sonic difference, then I do not have an answer to my question.

Right -- this is not that question or inquiry. That question leads to interminable debates about "tubes vs. solid state."

My question is very specific, and it’s intended for anyone who has kept all of the variables the same except for a change of either or both tube preamp/amp to solid state for sonic reasons.

Perhaps this question is so specific it doesn’t really open a door to that many people, but given how much people swap things in and out of their systems, I thought maybe someone had had this experience.
