I used a Tandberg 310? to make live performance cassettes when I couldn't drag me Tandberg 9100 to the site. Although the cassettes sound good, the RR recordings were better and with much lower, unobstrusive tape hiss at 7.5 ips. Now I have a Pioneer 1500 which I can record at 15 ips but I prefer (as do others) the convenience of the Tascam digital recorders at 96/24. I prefer the digital recordings to the cassettes overall. The cassettes did have a wonderful, warm sound presentation. The digital recordings are more immediate sounding and noiseless.
