Previously overlooked technology has been perfected to extract much more of what's hidden in the music on vinyl records.

Accession phono preamp in black finish The resulting sound from the Accession hi-fi phono stage preamp is considerably closer to the music laid down at its recording. Keeping Interference Out The Accession goes further than ever in keeping interference out: it has a solid ground plane board; multiple layers of radio frequency filtering; high immunity design, and the V2 casework has stainless steel "gaskets" behind front and rear panels which seal against electromagnetic disturbances - they provide conductive shielding in contact with board grounds which anodised aluminium panels alone cannot do. Side view showing the stainless steel EMC "gaskets" Record Equalisation Isn't What Most Think It Is Its design recognises something virtually all other phono preamps don't - that record equalisation isn't what most think it is! Record equalisation is quite a convoluted process complicated by historical and physical technical limitations - for records to work at all required some considerable compromises simply to cut and press the groove.

This is why record EQ exists and why the phono preamp has the job of correcting it. But there's something else contributing to the EQ which the phono preamp has to correct — the actual cartridge being used to play records has a rising response. The Accession Hi-Fi Phono Stage Preamplifier Changes It All Treating the two quite different EQs separately, the Accession first strips away the cartridge's contribution to the frequency response.

It then deals with the record EQ. Thinking about it, the record's own EQ was applied when the record was recorded, and even if you just bought the record you're playing today that event happened some time ago — whereas the phono cartridge is applying its rising response in real time now as the record is playing — these are two completely separate events in time. Single Slope The combined "EQ's" make up a complex curve of different slopes pictured below.

The solid black curve is the signal the phono preamp receives at its input. This is what the Accession hi-fi phono preamp stage does. It "EQ's" the cartridge first of all so all that is left to do is EQ the record's contribution, which it does in its second stage.

Rotating the curve only takes a single opposing filter slope to do the job. The cartridge "sees" a constant load and that's quite different to the conventional way of doing things — it makes a big difference to how it sounds. But it's not purely subjective.

High frequency distortion just melts away... just
