Your Forever Pieces? What and Why?

Correction. Hifi and tape. 

Probably my McIntosh C2500 tube preamp and MC452 solid state power amp...maybe my Focal Sopra No2 speakers and JL Audio F113V2 sub woofers.
My all-digital sources are probably the things that will see the most improvement in the future, not so much with amps.  Love the Focal/JL sound quality, they work well together and with my amp.

KTM 1290 super duke se decat sounds beautiful. :-I.  I've moved several sota speakers thru my system in the last 4-5 years but the pair that isn't for sale is the VA beethovens.

+1 for the Super Duke Steve!

Very nice!

I remember my old 900 Monster was good fun and had quite the rumble under full chat or blat as might be a more accurate description of the unusual v twin sound.

@bdp24 I probably asked you this before. I have a (treasured since 1987) Mk7 SuperGold with paratrace fineline too. It's due a retip amd I was thinking about adding a Decapod. I read another opinion saying it took away something, a certain life in the music. Could you kindly let me know your thoughts?
