The Aries is too large to fit on a Mana stand or wall support. The recommended minimum Aries shelf footprint is 16" x 22" whilst a Mana rack's shelf measures approx 15" x 19".When the Mana support was first sold over a decade ago, large turntables like the VPI were in the minority(particularly in the UK) and the LP12 was in it's heyday.
You'll also note that most Mana shelf spacings are perfectly spaced to suit Naim electronics and are too tight for many other equipment lines.It appears that the product was primarily built and designed to suit John Watson's personal tastes and favored equipment rather than intended from the outset to meet the needs of a broader audience.
