I have no objective observation to offer here.
Subjectively though, we have a loaner tape from Bruce for our R2R and there are tracks on it that are so enjoyable, so "high fidelity," that I am at a loss for words. Indeed, we made those tracks the primary demo material for our Mark Levinson/Revel system, making the digital second priority. I don't have an explanation for the observation as I don't have the digital versions of the same file to compare. It matters not in that I have the R2R and it exceeds the level of fidelity I desire in listening to the music. I was just listening to it yesterday and it was indeed the high-frequencies that caught my ear in the one track. It has a certain quality that I was not used to (in a good way). Maybe it is just the recording. I don't know. But the total package works and works very well.
BTW, there are passages in some tracks that peg the VU meter to the right. So much so that at first we thought the deck was broken. Then our main designer came and explained that when in his music recording business (he has a small studio), he would use that tactic on tape to get a nice effect on drums and such. It is remarkable to see that meter peg to the right yet not hear what in digital which would be a disaster. So perhaps it is the lack of the hard limit. I don't know. What I do know is what I said: that the tape achieves a very high level of satisfaction, its specs to be damned.
This is the first time I have been able to evaluate tape properly. The reason is that it has music that I like and am familiar with. The stuff that comes out of Tape project and such don't appeal to me and as a result, doesn't engage me in a serious way.
I wish there was a time when we could all get together and hear the same things. Without that point of reference, it is hard to make progress on these discussions. Summer is beautiful in Seattle. Maybe we should have an event here, making a tour of our place, Bruce, Mike, etc. What say you?
