These releases on 180 gram vinyl are aimed at the audiophile market. Members of the Hoffman forum have been buying audiophile jazz LPs (which they call "vinyls") for years now, for premium prices. Many are now OOP and sought after. Especially companies like Acoustic Sounds and Mobile Fidelity have been active in this field, issuing remastered Blue Note, Riverside, Prestige, impulse! and Miles Davis albums on "top quality vinyl" - and some also on hybrid SACDs.
