I have been playing with what I call "On the fly remastering" of marginal recordings for many years and have accumulated quite a collection of gear to modify and correct different issues. My Pioneer SX-D7000 has three tape/processor loops and each has a DBX Program Route Selector that takes my total number of tape/processor loops up to 21. Each item was purchased for a specific album or CD. Because everything is on individual loops, I can put any or all of the processors in the loop or listen to a record with nothing in the path. There are over 100 interconnect cables on the setup.
Here is the list of signal processors:
(3) DBX Program Route Selectors (each adds 3 tape loops, 3 processor loops, and a noise reduction loop)
(2) BSR Spectrum Analyzers (one at the beginning to see the clean signal and one at the end to compare the modification)
Original DBX 3BX with remote (remote is next to listening chair)
Pioneer SG-9800 Equalizer
Pioneer RG-2 Dynamic Range Expander
Pioneer SR-303 Surround Processor
DBX 224 with Disc Decoder for DBX encoded records
Behringer Composer XL with DeEsser for removing sibilance from CDs (such as Heatwave - Too Hot to Handle)
BBE 482i Sonic Maximizer for adding life to old recording from the 50's and 60's
Grant Fidelity B-283 Tube Processor for mellowing out digital music from CDs and streaming
MXR 5-band Equalizer (next to listening chair for minor adjustments)
DBX 3BX DS with Impact Restoration
DBX 120X DS Subharmonic Synthesizer
KLH 7000A Transient Noise Eliminator for ticks and pops on really old records
DBX SNR-1 Noise Reduction for removing the slight hiss that the KLH 7000A adds
While I am at it, here are my input devices:
Technics SL-1600 MKII with Shure V15 type IV and Jico SAS stylus (for records in mint condition)
Technics SL-1610 MKII (black version) with Shure N97xe
Yamaha CD-2 for older CDs
Onkyo C-7030 for newer CDs that won't play on the Yamaha (non-standard and extended discs)
Xiang Sheng DAC-01A (same as Grant Fidelity DAC) for the Onkyo digital out
Pioneer CT-F1250 Cassette
CSC MP3 CD processor (these were used in department stores to play background music. I modified it use a hard drive to store and playback files)
