An audio component you just can't let go

Advent 300 receiver, with the preamp designed by Tom Hohlman. Circa 1976. Used as a preamp only for decades.

I ripped all my CDs onto an external hard drive, but still am super fond of my Oppo 105 CDP.  Of all the components I have had over 50 years of having good gear, the Oppo DAC's are the best combination of sonic excellence vs. price.  

I have had all of Don Sachs interations of octal tube-based preamps and his newest one is the best of all of them, but all have been immensely excellent.  

Cary cad-300 SEI Integrated. It has all the upgrades and I love it with the Golden Lion 300B's. Great for both my DeVore's and my HD800's.

All of them !  Plus their boxes stacked to the ceiling in the garage!  But if it's just the main ones i don't use any more but remain in the rack for aesthetics:

Nakamichi CR4 Cassette Deck

Akai GX-265 R2R deck

ADC/DBX SS-525X Soundshaper Equalizer/Pink Noise Generator/Analyzer

Infinity RS Kappa 7 speakers, bought new off a dealer's showroom floor in 1989ish.They have managed to survive 30 plus years of my life, but with some wear. These were my first audiophile purchase, and are incredibly important to me.

I had the foam surrounds replaced for the woofers, Millersound refurbish the Polydome midranges, and luckily the EMIT tweeters have survived.

I had GR-Research update the crossover networks with modern and much higher quality resistors, caps, air core inductors, bypassed the pots, replaced the internal wiring with OCC wire, and added WBT speaker connectors.

They sound amazing! But I've spent several times more than what the speakers are worth, but to me it was worth every penny.
