The impeccable sound of the Accession stereo phono stage preamp takes music from vinyl and sets it on a new higher pedestal – it’s what all vinyl lovers will want to hear.
Previously overlooked technology has been perfected to extract much more of what’s hidden in the music on vinyl records.
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.
The package of features the Accession phono preamp provides makes it really flexible allowing it to fulfill a number of roles.
- Adjustable and fixed level outputs
- Volume / output level control
- RIAA, NAB (American) and FFRR (British) vinyl record EQ’s
- Flat / CA (constant amplitude) alternative EQ
- Mono / stereo switch
- Four cartridge capactive loading options: 100pf; 220pf; 320pf and “out”
In a frugal or minimalist vinyl only system the volume control lets it drive a power amp (we suggest a pair of Proprius), and the fixed outputs can drive a headphone amplifier.
As part of a “traditional” system the variable outputs can be used into an ADC or sound card to do “vinyl rips” while the fixed level output is connected to your preamp, integrated amp or receiver for normal listening.
The different record EQ possibilities make it great for archival duties if you have old mono LPs and EPs which don’t sound quite right.
