Listening Tests, part I

We have decided to perform a listening test of 2 full systems--expensive and moderate. These systems are comprised of the following pieces of gear:

1. expensive: VPI HR-X turntable, Manley Steelhead Preamp, and Ortofon Kontrapunkt a
2. moderate: VPI Aries 2, GSP Jazz Club, and Ortofon OM20

Each setup is then fed into the analog inputs of the PrismSound ADA-8XR, and recorded using Logic 7 on a Mac G5 in 24-bit 96 kHz digital audio.

According to several reviews of the Kontrapunkt a, optimal sound is achieved after a number of hours of listening (many reviews state 10+ hourse are adequate, and some accounts list >100 hours!), so we are currently working towards this goal (we have also made a recording with the fresh cartridge for a potential later comparison).

J, Atkinson RIAA error

J. Atkinson of Stereophile has graciously provided us with his code for a RIAA measurement from 10Hz-100kHz. Our current RIAA measure only goes from 20Hz-20kHz because our RIAA deemphasis curve is limited to these values. Thank you Mr. Atkinson! We will test this once back from Utrecht/Athens.
