Anyone else constantly curious about amps?

Interesting timing with your post.  I just setup my system at our summer place. I had removed all of the equipment except for the dipole tower speakers I got used so I could let them stay the winter without worrying.  Acquired a more powerful used amp over the winter and was planning on upgrading the speakers.  I streamed a few tracks and played a CD and I couldn’t believe how much better the speakers sounded.  I’m set for now.  Glad I didn’t get another pair or speakers since I’m trying to consolidate what I have.  We all give you the push you need to buy the amp of your dreams!  Side note, I’m getting too old to lug gear back and forth.  Everything stays from mow on.  If the mice want to jam in the winter they can.  

I too am one that what ever I get into I’m all in.  But I’ve learned it’s as much about the chase as it is the capture.  I’ve also learned I can not trust my own logic as to what I need to make the next step.  I have to seek expert unbiased advice.  
One thing I have learned is I am a tube amp guy.  I can listen for 8 hours plus and never fatigue.  With solid state or hybrid integrated amps after a couple hours I am worn out.  Now that my be peculiar to me but at least I’ve eliminated a large section of the amp market.

Thats my experience and opinion which in the big scheme of life is meaningless.

I’ve owned SS, hybrid and tube amps over the years and found all can provide quality sound.  The best part has been the experience in the exploration of each type!  I’m currently running a powerful Simaudio Moon SS amp that is wonderful paired with a tube preamp.  Time will tell if I’ll want to go back to tube amps.  

Curious about amps? How could you NOT be? I'm with you!

Why? Because there is no such thing as a speaker on its own. The basic unit is a speaker-amp. Their pairing is about "synergy" which means not just "sufficient power" but "pleasing interaction." 

In my room, I have had:
Class A:

• Pass XA 25
• Pass Aleph

Tube:

• Linear Tube Audio ZOTL Ultralinear+
• Quicksilver Mono 60 tube amps

Solid State:

• Adcom 535L
• Benchmark AHB2
• Hypex-based Class D amp built around Burson OP amp.

And everything has been tried both with a very neutral SS preamp as well as with a tube preamp.

All these amps sound different. And not just better/worse but different. And I've tried many of them with different speakers.

The point is that the investigation of "synergy" is a key part of what I'm interested in, and trying different amplifier-speaker combos is the heart of it. And if you're settled on your speakers, what more could you owe them, and your system, than to try out the right amps until you find what brings out their potential (for you, in your system)?

That's one of the nice things about tube amps.  You can change the tubes out relatively inexpensively and change the amps sound, giving you a new experience each time.
