I have the same problem with audio gear as I do with bikes - always think what I have is no good, and I miss what I've sold more than I like what I have.
All my audio and video is stored on a Synology NAS, so I don't use a regular front-end source.
Downstairs
I sold a Cambridge Audio Azur 851N because the streaming functions were no use to me. Obvs I regret this now, but given that I mainly listen to the radio and like having it playing to several rooms at once, I bought Chromecast Audios - which was a big move for someone that can be snobby about front-ends - but a £20 device can play lossless files and has an optical-out. I like DACs with integrated preamplifer functionality, so I use either:
- A Pioneer U-05
- Or a Marantz HD-DAC1
I still also miss the Audiolab M-DAC I used to use. Sometimes I think I'm going to buy a Naim V1 DAC but circumstances mean I am less easy-going with buying new stuff.
- 2 x NAD C275BEE power amplifiers running in bridged mono. I've never been interested in numbers before, but this gives 330W per channel. I was using a 30W Naim amplifier for years, it was only relatively recently I started using more powerful amplifiers; speakers sound 'bigger' and low end is completely different, I stopped using a subwoofer.
- Martin Logan Montage speakers - super-dated floorstanders with electrostatic tweeters. I've had these ages and will never part with them.
Loft
Home theatre with an Epson 1080P projector and a 100" fixed screen, but I wanted this to work as well as a stereo rig. Front end is either an NVIDIA Shield or a Chromecast.
- Rotel RSP-1572 AV preamplifier. I was adamant I was going to run this in 2.1 as I always thought multi-speaker rigs were a gimmick, but I did end up getting some rears and have it set up 4.1.
- 2 x NAD C272 power amplifiers in bridged mono for the fronts
- 1 x NAD C270 for the rears (although I will change this for another C272 when one comes up)
- Mission 783 fronts
- Monitor Audio Bronze FX rears
- REL Storm subwoofer
Other things - that I use in a spare room, I don't use the headphones as much since the Doris flew the coup:
- I've got a ridiculous collection of Grado-style DIY headphones. Like more than half a dozen pairs?
- Fostex TH-900 headphones with Lawton Audio cups
- Chinese clone of a Quad 405 power amplifier
- A pair of Mission 782
- A pair of Musical Technology Kestrels. Had these since I was at college and will never part with them.
- REL Strata, redundant from the living room rig.
- Pioneer stable-platter CD player (I forget which one, its nice though)
- And some Bose stuff for the kitchen and bedrooms
