OK, but there is a better way, not requiring subjective opinions in real time.

As it should - whether solid state or tubes!
Solid state or tubes, it’s all good. The only way you’ll know which you’ll prefer is to listen to a few different setups. Of course easier said than done, so another way to go about it is to buy used and experiment that way.
Modern tube gear and vintage tubes are my preferred listening medium. Currently listening with 5 tubes in each of my mono amps and 9 tubes in my preamp. Even my DAC has 3 tubes. None in my turntable though 
Really glad I entered the tube rabbit hole about 10 years ago. Enjoy the journey.
Scientifically speaking, tubes are bad for audio in the sense that they introduce more distortion. In terms of experiencing audio, many people enjoy the distorted sound. Just let your ears decide what your preference is.
What Bergh just said I did. I compared Lyngdorf, Liner Tube Audio, Odyssey in my system in my room side by side. I listened and also brought in my Wife and adult Daughter to listen. The Wife and Daughter have bat ears and this has been verified by audiologist testing. They also have zero understanding of the hardware they were listening to. All of us chose the Lyngdorf class D. I hated the results because I LOVED the looks of the LTA components. But alas, all went back but the Lyngdorf. The Odyssey was a huge disappointment. The LTA was a close second but seemed to change the sound in a way none of us liked. The Lyngdorf acts like a wire with gain. That’s my story and I’m sticking to it!
I’ve since built two Pass DIY amps. They are very close to the Lyngdorf but the class A also gives it a different sound. I would be happy with either topology. But still the Lyngdorf is my go-to amp for the most accurate sound in my opinion.
Out of interest, did you/are you using room perfect?
Tube gear can sound fantastic, but it’s not for the casually committed. Tube preamps with current production tubes or NOS tubes bought from the handful of reputable specialist dealers (e/g Vintage Tube Services) are the least stressful way for most to dip their toes in the waters.
Tube phono stages are dealing with signals 1/10 the size of other signals, so much more sensitive to noisy tubes, RFI, etc. Great for more experienced folks not surrounded by radio signals.
Tube power amps are much easier for newbies if they are autobiasing(e.g. Balanced Audio Technology). The higher cost/watt means more care needs to be taken in matching your modestly powered tube power amps with easier to drive speakers(both in terms of sensitivity and impedance curve) If those two aren’t familiar, please do some research before selecting a tube amp & speaker pairing.
No I wasn’t using room perfect during testing. In fact I still don’t use it with the Lyngdorf. My room works well without it. I’m a less is better person. I did a LOT os work on room acoustics to eliminate additional signal processing.
Interesting. I admire your conviction. I would have to out of nosiness.
Thank you for that brief but information packed summary of why I don’t use tubes 
I find the tubes versus solid state argument to be similar to the analog versus digital and the disc versus streaming arguments. Sure tubes sound different than solid just as analog sounds different from digital and discs, especially LPs, sound different from streaming. At this moment in time what the solid state/digital/streaming side each argument has going for it is ease of use, with what I feel is audio quality on the same level as the tubes/analog/discs side.
So while tube rolling and LP spinning may provide for many individuals, this individual spent too many years dealing with the various inconveniences of LP and disc playback to enjoy the ritual of playback. The way I look at it is the sound I get from streamed digital audio driven by solid state electronics is very good and is at least the equal of disc/vinyl analog audio driven by tube based electronics. Like a stated earlier the sound may be different but the differences are more of personal preferences rather than audio quality.
Hi, There have always been two systems of thought for the manufacture of amplifiers: tubes or transitors. The tubes were abandoned (not really) for the reasons you explain, in addition to giving a sound that some call “warmer”.
As far as the High End amplifiers built by Thrax are concerned, not only do they not have this sound defect, nor the hum at low level, but they reproduce a totally natural sound. The message that enters the system is exactly the same as the one that comes out of the speakers. This is a sound engineer’s opinion who recommended this equipment to me.
Finally, the THRAX system is a bit of a hybrid in the sense that the tubes are controlled by supporting electronics.
But of course I don’t want to enter in the discussions resulting from the “nest of certainties” between the interest of the tubes vs the interest of the transistors. Everyone finds what he wants according to his ears. Any other audiophile debate always seems to me a bit vain. Enjoy the sound you like. That’s all. Thanks.
600W into 8Ω with a hybrid amp. Modest is relative I suppose.
Freya+ → 2 X Aegir monoblocks.
Lovely tube (Sylvania “Bad Boys”) into a couple of “almost class A” solid state amps. Source is an Yggdrasil LIM, and driving a pair of the new KLH Model 5’s. Makes me very very happy.
Guess I’ll have to beg to differ. Using Conrad-Johnson’s finest class A tube amplifier with custom Lundahl output transformer driving Wilson speakers voiced with high power tube and SS amplifiers, the sound is to die for. The dCS front end makes Roon magnificent.
The power supplies in good amplifiers have more effect on the sound quality than the amplification devises.
Well, @Floyd_Toole did say “almost always”, not “always”, so a counter-example doesn’t invalidate the statement.
Some people have a vested interest in peddling one idea though. I enjoy reading advice from the majority of people as I like a balance. I especially seek out information from people who don’t tend to have a bias or invest in solid state and valves.
Tim de Paravicini was one of these people and I believe Macintosh and audio research have each made quality solid state and valve amplifiers. These were/are the people who I would take seriously as I wouldn’t feel that there was any agenda.
The argument that one technology is better than the other is nonsense anyway, when tens of thousands of people use both of these technologies every day and like it. A well constructed solid state/ tube amp is always better than a poorly constructed solid state/ tube amp and vice versa. It is just different. Let’s embrace differences here and not get bogged down on this or that (even though it is entertaining to argue ;).
BTW would you all hear the difference between these technologies in a blind test? I am not so sure. I have never tried it but I can say from my tube headphone amp that it doesn’t sound tubey, or whatever that would be.
Excellent point! “Better” is a scalar quantity in a multidimensional vector space.
@Bill_Janssen Come on fess up - you stole that line from Star Trek 
I had dog here in Brasil that was almost a dead ringer for yours. We adopted him from the street and he lived a happy, stubborn life with us for 15 years. He is greatly missed.
