Think about this logically for a moment. What is the main thing that fails with a tube amp?? The tubes, right? The rest of the amp is usually very simple in comparison to a SS amp. When tubes fail they are simple to replace, no? Even if you have to bias them (many amps you don't need to do this) it is still a 10 minute job. The circuit is usually simple enough that if more serious problems arise a skilled technician can reverse engineer the schematic.
Now, when a transistor amp fails...well it is usually pretty terminal and requires a very experienced person...and a good schematic in order to repair it. It will not be possible to reverse engineer the schematic in most cases.
Now, while I will agree with you that an SS amp will fail less often in general (there have been notable exceptions to this...you just have forgotten your history), when they fail it is often catastrophic. A tube amp might fail more often but 80% of the time it is a simple tube swap and then off and running again for another 5-10 years.
You and some others seem to be making a big noise about tube amp problems but they are relatively unproblematic in general and easier to fix when things go wrong.

Morri, Really..!
You can have your subjective Sound with Tubes, But there is no way you are going to convince anyone tubes are more reliable than SS, funny stuff thou...

... and at 86 I'm sure interested in reliability. The last two failures I had -- earlier this year -- were of solid state gear. That's been the pattern throughout my history with this hobby.
Yeah, I'm sure there are badly made SS gear , a rarity thou with SS , failures that is ..

Rare, you say? My tubed audio system (it's in Inmate Systems) is reliable, extremely musical and involving, and a joy in general. My solid state HT setup (Sharp Aquos TV, Marantz receiver, Oppo Blu-ray/DVD player, Comcast cable box, Apple TV, multiple HDMI cables) has been nothing but trouble. I'm on my 3rd cable box, 2nd receiver (and the second one is just as unwillng to work with the TV as the first one was), I'm currently reduced to going straight from the cable box to the TV, thus eliminating the benefits of external speakers and the option of headphone listening. A tech shop recommended by Sharp has tried hard to solve this problem and ultimately given up.
Oh, and the furnace room is a museum of non-working stuff, all SS, that I think MUST be fixable because SS is so damn reliable, don'tcha know.
Sorry to hear this Dave , now a show of hands , anyone with a collection of bad SS amps, err, excluding cable boxes of course .. :)
Sorry Dave tooob's can't win the objective reliabilty test , not possible , why AR alone keeps fedex humming :)
"collection of bad SS amps"
No, because they get chucked out like yesterday's newspaper as they are either unrepairable or not worth repairing in the first place...
What about bad Feedback SS , euphonics with reliability ...:)
Looks like something was not adjusted properly in that amp or there are design flaws. It is using optical biasing of the output transistors and who knows what kind of non-linear can go wrong there?
Certainly won't sound like a good tube amp...particularly a SET.
Morri,Do you level match when comparing side by side or are your comparisons memory based. Some years ago , I did anger a bunch of my ESL biased friends , after they requested to turn off the "slow" subwoofers , of course i only pretended to power them down and the night went on without a nary or a hitch ..... :)
complaint free Audio And so it goes .....

I level match using a Behringer DEQ 2496 digital equalizeer and pink noise generator to set usually within 1 db. Works quite well acutally.
I have found that a good servo sub can keep up with planars and/or horns without an issue. If you have some phase control then you don't have to get all crazy about placement, however, I have found that for time coherent speakers it is really critical to place the sub in as close to a time-aligned placement as possible or it will sound slow.
My Mirage BPS210 works well when placed correctly. The only drawback it that it will not play super loud. It is very "fast" though and has a lot of controls for blending with the speakers. I get a great blend with either my Ref 3as or my Odeons.
JA goes on: "Below that point, the Edge does offer excellent measured performance; above it, the extra distortion on musical peaks will only last for the duration of the transient, which will work against audibility. Only on sustained high-level music will the Edge's sound become harsh"
In other words, a POS.
I love the music of Dmitri Shostakovich
No , a Euphonic power instrument and with the right matched setup will produce toob like euphonics of added ambiance and reality ..
So it goes ....
@Mel, take a look at the ATI amplifiers , very robustly built , not sure of the sonics , trying to ascertaining that myself ...
