Tinny sound accompanying cello on recordings ?


I'm somewhat baffled by an on and off tinny sound I've heard on several recordings of Dvorak's Cello Concerto. Up until a few years ago, I either didn't hear it or didn't notice it. The more revealing the sound system, the more obvious is this phenomenon. At first, I thought something was wrong with my speaker drivers, but when I listened through other transducers, I noticed the sound was still there. I proceeded to isolate the rest of my equipment, but the rather unwelcome "guest" remained. It didn't matter whether I used the same recordings with a cd player or a phono front end, things didn't vary. I listened to identical passages of the Dvorak Concerto with Fourier/Szell and Harrell/Levine. I haven't yet bothered to check other cello recordings. This tinny/sizzling sound is a shadow-like resonance hovering around the cello's notes as they are being played, asserting its presence more frequently, it seems, from the mid to upper midrange. I assume some of you classical fans have heard this. Can anyone explain exactly what's going on here ? By the way, I hear it also (though less obviously because of the much smaller sized sound system) when watching and listening to the same piece performed by Rostropovich on You Tube with my computer and its little Altec speakers. Listen in particular to the first movement from the time the cello enters, and onward.

Dougdeacon...No need to apologize about the "threadjack". Your comments/observations are never less than interesting and insightful. Frequently funny too, and that is certainly welcome. I also just wanted to mention something in response to your remarks about the effects of cleaning lps. I recently compared three copies of the same recording. Notwithstanding wear (though with all three wear was relatively light) and the matter of earlier vs. later stampers, I decided to clean one with a 75/25 mix of very pure, triple de-ionized water/99.9% pure isoprophyl, and another with a highly regarded (at least, here on Audiogon)record cleaning rinse. The third copy was simply left alone, never having been cleaned by me (only the Audioquest record dust brush) since I had purchased it. After listening intently to all three several times, this is what I heard: The sound of the one cleaned with alcohol/water presented considerable detail, top to bottom, but overall seemed just a very slight touch bleached in contrast to the copy cleaned with the commercial solution. In turn, this latter copy seemed to compromise slightly the top end detail of the alcohol/water disc, while giving more presence to the midrange to lower midrange. To my ears, the record left alone seem to have displayed the best balance in sound of both of the aforementioned discs. This was not the first time I have experimented like this, with the results being the same. Unless a record really needs a cleansing, my preference dictates laissez-faire. Does anyone else care to comment on whether they've tried a similar test, and what they found/preferred ? Now I seem to be "threadjacking" myself.
Mental strings versus gut strings are TOTALLY different, as the string players above can attest to. It is always great to sit down and compare are 17th century consort of viols to a modern chamber ensemble playing the same piece

For those interested there is Chris Hogwood's stuff "Academy of ancient music" done on period instruments or reconstructed instruments like what they would have used...I have a fair number of his recordings and like them.
Shadorne,

Hogwood's AAM recordings are our daily fare. Superb stuff, played by the most amazing musicians anywhere. When we want to test a system we always bring an original/authentic instrument LP along. It's very easy for a system to make them sound horrible and unmusical. It took us four years to get ours even close to right.

Opus88,

I dearly wish I could duplicate your results and practice, but our cleaning experiences differ. Your system's not listed so it's difficult to evaluate your results or what they might mean. Also, you didn't mention how or if you vacuumed the fluids off. If that vital step isn't performed properly the whole concept of wet cleaning falls apart, and can easily do as much harm as good.

The only consistent result we've achieved by playing uncleaned LP's is to ruin them, so I'm not eager to repeat the experiment. Unfortunately for my time and budget, our present cleaning regimen (which would drive most people nuts) invariably improves low level detail and subtle dynamics.

Assuming you're vacumming effectively, a final rinse (or two) with some very pure water (better than just 3x deionized) is essential to our cleaning regimen and sonic results. Try repeating your experiment with some MoFi water, if you care to spend the time and money of course.
Doug...The commercial rinse I used in the cleaning of one of the records was the latest [Mo]bile [Fi]delity. With the other disc, I mixed the 99.9% pure isopropyl with water that goes through a multi-step process which, FWIW, claims to achieve "about the theoretical maximum for ultra-pure water". Also, I did and do vacuum with the VPI record cleaning machine. As indicated, I've experimented several times with this ritual. Here are/have been my components: VPI HW-19 MK 3 and Teres 265 turntables, SME IV.Vi tonearm, Zyx Airy 3 and Dynavector XV-1S cartridges, EAR 88PB phono preamp, Air Tight ATM-3 monoblock amps, Dunlavy SC-4 speakers and Ridge Steet Poiema 3, Poiema 3 Signature and JPS Superconductor 3 cables and power cords--all in all, a pretty revealing system. I doubt I'm as thorough as you are in your cleaning process, "...which would drive most people nuts...", but I feel I do a decent job. Anyhow, all things considered, of course, we are dealing in part with the subjective element in evaluating outcomes and the usual YMMV,etc.
