Results of Testing my Turntable using the HiFi Sound HFS75 Test Record

My turntable is a Linn Sondek LP12. It was originally purchased in 1980, and has since then had all of the major upgrades up to and including the Lingo power supply. It has not had the Cirkus or any subsequent upgrades.

The pickup arm is a Linn Ittok LVII. This is a fairly early Ittok, with the two-piece counterweight.

The cartridge is a Linn Karma AL22621. This is a low-output moving coil type. Although I have had this cartridge for several years, inspection does not show any noticable stylus wear, and it still sounds fine to me.

The phono preamp is a Naim 42.5, with K series input boards made specifically for the Karma.

The soundcard used is an M-Audio Audiophile 2496, and all recordings were made in 16 bit, 44.1kHz, stereo. The recording level was left set to a typical level that I use when transferring music LPs.

The results of the tests are downloadable below. All the download files are FLAC lossless compressions of the original WAV files as recorded. To reduce the size of these files, I have included just a few seconds for each test. Since they are basically steady-state signals, I saw no reason to make them any longer.
