R2R for High Fidelity audio can be a challenging and time-consuming hobby. (Been there, done that, got the T-shirt.)
Results are dependent upon the quality of the tape stock, the accurate adjustments of both the record and playback heads, the quality of the transmission of the waveforms from input to the tape - - and the capability of the owner not only to replace and align the heads, but also to cut and splice tape.
If you think setting up a turntable, tone arm and aligning a cartridge are time-consuming, try to align replacement separate record and playback heads in a 10.5"reel R2R. It takes both special equipment and loads of patience.
If you record live music, or transfer LPs to the machine, you'll soon become adept at the "Cut and Splice" capability needed to use a splice block, new razor blades and splicing tape. Lotsa' fun!
I had two R2R tape decks, but had to give them up when the manufacturers quit making the playback heads. I was stuck with unopened 10.5 reels of Ampex stock, plus many reels of recorded classical music. $$$$ just sitting there.
Guess that what convinced me that the little CD s were relative bargains - - and the playback equipment no longer a hassle.
Just the Saturday morning thoughts of a now-contented CD listener.
