whatever works i guess, i just can't get myself to actually listen to anything taped with ECMs. the tapes tend to sound really brittle and dry and unfortunately the majority of metal stealth tapes are made with these things. then again I've been called a gear snob and i'm very picky about sound quality, so do whatever works for you. just don't expect these to sound any better than the standard ecm tapes that flood dime and ttd.
