I just finished recording the Classic Records 45rpm Led Zeppelin set in 24/192 ALAC with an 18 Hz 48dB/oct digital rumble filter. On my system using 8 foot 645 Sound Labs electrostatic loudspeakers nobody can tell the difference between the actual record and the digital file. I must have run that comparison 10 times by now.
I also got the MoFi Rolling Stones set and much more to come. This is way superior than recording to any analog R2R machine and once you own the program and electronics, free of charge. I am thrilled to death with this capability and highly recommend it to anyone with access to large record collections. That LZ box is now on the market for $12,000!
