Yes, there is. In your case (and in most cases) it would be appreciably better to listen direct but I get the impression that what you've got now is just the turntable, USB interface and computer. If that's the case then I think you need a step-by-step upgrade program.
Your key initial objective, IMO, should be to get away from the USB interface for the actual phono-stage duties because the Behringer won't be much chop in that area, frankly.
The most obvious first step as far as I can see is to get hold of an '80s-era integrated amplifier with a phono input (on the assumption that you want to do this on a tight budget) - something along the lines of a NAD 3020 would do fine. Not a permanent installation, to be sure, but cheap and already better than what you've got now. You might be able to connect the speakers to the amp (no idea how the Logitech is connected) via the speaker outputs or, maybe, a pre-output. The latter facility is rare in cheap integrated amps but the good ol' 3020 has that feature too. You can still use your Behringer in this configuration. You switch it to line input mode and connect it to the tape-out sockets of the integrated amp while feeding its (the Behringer's) output to the tape-in sockets of the amp. In this way the computer becomes a virtual tape deck and you can listen to anything on the computer through the amp by selecting "monitor" on the amp. It's the same for any integrated amp of that era.
The speakers would be next in line for upgrading and with freedom from the restriction of "computer-output-friendliness" you'd have a vast choice because you've got a real amplifier by this stage.
Then I'd turn my attention to the turntable itself and look for something with better pedigree, again second hand from the golden era - there are bucket-loads of good suggestions on Vinyl Engine and you'll need to look at your cartridge options at about the same time.
By this stage, if you've chosen wisely, you'll have a really nice starter vinyl playback system and my suggestion at that point would be to get a better computer interface.
I realise there's some analog-to-digital chaos in that picture, but I do have the ability to line out directly from my pre-amp without having to go through the computer.
Mmmm... If you're talking about the UFO202 then you might like to check that again because I've got a feeling that the line sockets will only feed output when connected to the computer, not looped though internally.
