The more and more I read this debate or quandry or whatever you want to call it, the more Im thinking people are really not seeing the core of the issue at all. If you are a good engineer, you'll be able to make a good sounding record on a tape machine or a computer. The process you need to go through to get there is vastly different for both mediums, but you can make a good recording on either if you know what you are doing. I dont see this as a debate of one medium sounding better than the other, and as digital technology progresses, it becomes less and less and less of a debate every day. I think the stage that we are at now, is in places where digital systems get a bad wrap for "sound" its not the digital technology but the cheap consumer crappy front end that many budget systems are stuck with, and THAT is what sounds bad and if you hooked up a tape machine to the output of an M box or something cheap like that, it would sound bad too.
The real issue, more and more in my experience, is the process. I think its REALLY important for a singer, for example, to have that little break while the machine rewinds between takes. It doesnt seem like much, but its HUGE over the course of a 10 hour vocal session. I cant even begin to think of how many good ideas Ive had waiting for a machine to rewind. That built in time is worth its weight in gold. There are many many many things like this between both platforms. The resolution at which you are able to tweak is another point of contention I have... It goes on.
I dont see the decision so much any more to do with what sounds better as if you know what you are doing, you'll be able to figure out how to get your sound on either platform. Its more about what you are trying to achieve and which platform is more appropriate from a creative perspective. I have trouble understanding why you'd want to do say, an electronic music project on a tape machine the same way I have trouble understanding why you'd want to do a straight forward rock record on a computer. Everything has its place from the perspective of the work flow, but I think the technology is at the point where the sound of it really isnt so much of an issue anymore. Sadly, people with digital systems have been lead to believe that you can get "professional" results for cheap. Most of the commercial studios I have been to that rely on computer platforms are still using a computer in conjunction with a very expensive console, so I dont know how realistic that expectation is. I mean, if you are mixing on a neve 8068 it doesnt matter much of the **** is played back from a studer or a macintosh, you know?
Anyhow, forget what the things sound like because you need significant investment to get a really good sound out of either platform right now, plugins are just a big distraction at this stage in the technology IMO. Figure out what benefits you creatively the best and then start building a system on that platform. Tape is cool, but I'd rather record kraftwerk on a mac.
