Last night I got in the mood to listen to a gem that I don't play very often, Harry Belafonte at Carnegie Hall. I have an original NM RCA Living Stereo two LP pressing with a sticker on the front proudly touting the virtues of RCA's "Miracle Surface" vinyl composition. I also have it on a single pre-recorded reel at 7 1/2 ips. (I also have a mono LP, but that's irrelevant.) This is a great record, extremely well recorded. Very natural live sound, you really feel as if you're in the audience.
Now, I put the record on last night and was enjoying it, but I was noticing quite a bit of sibilance on the vocals. I thought maybe my stylus was picking up some dust. I'd had a few cocktails, and was ready to go to sleep, so I didn't really feel like messing with the stylus and I decided instead to put the reel to reel on which I could fall asleep to without leaving the stylus in the runout groove.
Well, several things jumped out at me. First, all the sibilance I had heard on the LP was right there on the tape as well. The sibilance sounded so much like what I would have assumed to be a vinyl/playback issue but it was actually in the original recording.
Second, although my "Miracle Surface" disc is in great shape and pretty quiet, this record has a lot of quiet passages and beautifully mixed instrumentation with lots of low-level information. The total lack of intermittent noises (pops and clicks) on the tape was apparent and really nice.
Third, The LP had a presence and authority that the tape lacks to a noticeable degree. The tape still sounds wonderful and balanced, but just a bit thin and light in comparison to the LP. Now this may be more a function of my gear than the media. My cartridge is good but not great (Shure M75 with a hyperelliptical stylus). The table is very good, and the whole signal chain is simple and tubed. The tape playback is via a decent consumer deck, Teac A3300s, but the signal goes through the Teac's internal preamp (recently totally recapped with Elna caps). The Teac preamp is certainly inferior to the Audible Illusions phono stage, and that could easily be the source of the thinness in the sound.
In summary... there is no clear winner here. I think I prefer the "weightiness" of presentation that I get from the LP, but the clean background of the tape is really nice. The tape also has the edge in convenience... the double LP is in "stacker" sequencing, so playing it in order on a non-changer means a lot of vinyl shuffling. The tape has the whole thing in order with only one turn, and it's nice to have the length of both sides of an LP on each side of the tape.
Plusses and minuses, none strong enough to totally counter the other.
