Project X is alive and well playing music in Lossy and Lossless forms from my Fiio music players line output from one of Eight micro sd cards as well as from a elderly Toshiba cd player.
I like quite a few people have a good number of cassettes not least pre-recorded ones I bought from the mid 1970's to mid 1990's I moved from cassette based portable listening to MiniDisc and had been thinking of how to play them back on this mini system.
Enter a unused Sony TX 313 mini sized fully functional cassette deck from a MiniDisc system I got from someone who never ever used it so it was still boxed and shrinkwrapped from the late 1990's.
Oddly enough it uses a car type side slot way of loading the tapes into it but unlike car units this does record and has auto tape type sensing to read the extra tabs for type II ('Chrome') and IV (Metal) tapes although the latter are no longer available new plus I seriously doubt it's tape heads really are up to making full advantage of such tapes electrically
The rear has RCA line in and outs, with the out going via a expensive Cambridge Pacific interconnect to the input selector with a maximum of 0.5 volts out depending on the program loudness and the AV bus for Sony mini systems it was sold with for synchronized cd to tape copying.
The unit is blessed with switchable Dolby B noise reduction for proper replay and recording of such tapes plus auto reverse so it can play one side of the tape and switch by itself to the other.
According to the specifications it reproduces up to 14khz for type I tapes and 15khz for types II and IV which is decent if not as wide as most full sized hifi cassette decks so the high frequencies will be clear but not quite as extended as the best units can achieve.
It is making an excellent job of replaying my 1980's EMI UK dolbyized Beatles pre-recorded cassettes which were amongst the best sounded tapes manufactured and part of reason I held out so long against the cd as portable listening was and remains a big part of my life and why my Fiio is my 'to go' digital playing device on headphones or connected to this system.
I like high quality portable formats more
