AGD The Audion Mk 2 "GaNTube" amp.  Clever ( ? ) use of GaN amp board inside a tube structure, with up to 170 watts into 4 ohms.  Neat design, and I have a pair of mono GaN amps ($1500/pr) that likely sound just as good; so not sure it's worth the money to have it look like a tube amp.....  Third picture is the old vs. new version of the GaNTube.

 

 

 

This is only an updated version of the FETRON, introduced in 1972 by Teledyne. A thick film hybrid JFET amp in the header of something that looked like a nuvistor.

darTZeel monoblocks looks like chonky computer cases to me.  Their name looks like a "gamer" brand as well.  Frank Herbert once said he based the Harkonnen on the Swiss.  For Giedi Prime!

What is the white deck middle to the right, with both rotary knob, on the right to the Dartzeel pre-amp? 

I'd say it's a phono preamp, but not the EAR 912 which I thought it was

 

It sure has a nice finish.  I wonder what kind of noises it makes.  *squawk*

Some "old, beat up gear" given to a guy on /r/audiophile by his GF's dad.

Just a little entry level rig.

"If it's not for sits, why is it made of Class A?"

That’s one way to find out if cat fur is conductive.

I remember the school physics book that talked about generating static electricity. "Rub an amber rod with cat fur..."

I wondered whether this experiment had ever been tested by the writers of such books. Here kitty kitty kitty..

I lust after the Luxman B-1000F monoblocks.

Liked for the audio system AND the hockey....GO BRUINS!

Redundancy Central 

It's their best album, TBH.  \m/

DIY 300B monoblocks.

Left and right monoblocks are mirror images - that is a really nice touch. Hand cut dovetails are decent looking too.
