I know this post will reflect personal preference (if anyone replies), and i will use mine when i go to the store and listen to my reference disc. My small, 2 room project studio/live recording rig is due for a mic pre upgrade. It consists of M-Audio 1814, ART Pro MPA 2, Tascam 424 mk2 (6 channels, 4 tracks), 414 XLS, Sm 57, Nady Drum mic set. Mackie Hr 828 Mk 2, and a couple other budget rack eq's, efx units. There are Rockwool panels/ Uhaul padded blankets (ceiling, backwall) in the 'RFZ' control room (12'x13'), and 64 s.q.f of Aurelex wedgies in live room (12'x26'). These pre-existsing rooms were built using no isolation/techniques. I need an 8 channel lightpipe pre to make use of my interfaces adat ports, and will love the color that a higher end tube pre will offer me. My budget for this upgrade is between $2-3K. I will be patient if i try something that blows these out of the water for around $1k more. In use: I intend to market my registered sound business to area bands of any style. I expect to record in my studio, at bar/club gigs, practice spaces (quick, 8-10 hr. demo style sessions). The Question: Is 8 channels of ISA giong to benefit my business more than 8 channels octo/ 2 channels 610? Concerns: Thin/cheap sound quality, Spending ALOT more for not much more benefit on a 8ch workhorse pre, being a paid "professional" and showing up w/ a 4 track/M-audio interface for sessions. I appreciate anyone who replies to this longwinded post any options suggestions will be thought about.
