I think it's a bit of both. I don't think the TS2000 sucks as a receiver, either, it's QST review numbers were fairly decent. But sure, there are better rigs out there. I continue to be impressed with my ancient Ten Tec Omni VI+, and I know it's far from the best out there. I see that Inrad sells a 2.1 kHz replacement filter for the TS-2000. It's a pretty sharp 8 pole filter, that I suspect would be a huge improvement, at the cost of some SSB audio fidelity (but not that much). I presume it requires careful soldering skills to install this device, and I would suspect some realignment, too. http://www.inrad.net/product.php?pro...&cat=38&page=1
Some people do get too close to others - in some cases, they have better receivers. I'm probably guilty of this when I'm doing digital modes, because we digital guys can usually line up right next to each other - no space showing on the waterfall - without interference. Indeed, I find that Olivia mode can operate with one RTTY station right on top of it! Two RTTY stations are too many, though! Now, the guy operating RTTy is probably not as happy, and the guy operating CW 500 Hz away with a 2.7 kHz filter in his radio is madder than heck, probably screaming LID and cursing that he can't copy my callsign. But the PSK31 guys a couple Hz away from me on either side are happy as clams.
And, yes, if you're in between two other stations on 75 meters, it's entirely possible that they can both be clobbering you, and not hear each other. Propagation on that band is really pretty dynamic, and it changes fairly rapidly at times. I often see huge changes when I'm running my 80 meter digi nets. Over the course of one hour, close by stations will go from 20 over S9 down to inaubdible as the minimum skip distances change.
