[QUOTE="Steerpike, post: 293887, member: 807"] You need to look at the flux density at which those frequency response curves are made. A R2R can reach 22kHz at around -3dB when running at 15 or 30IPS. A cassette recorder can only manage 20khz at -20dB; they almost NEVER tell you the distortion figure. And R2R tape is almost universally ferric oxide, which for cassette gets a frequency response to about 15kHz only (at -20dB again). [/QUOTE]
