Cartridge or cable upgrade

Thank you all for the myriad avenues of advice and direction!

Now, let's assume that a new tt is out of the picture for now insofar as I'm guessing I would have to spend ~$1500 or so for a decent upgrade. And assume I have a few other bills I'm paying off before I go full throttle into the tt route.

So, with that in mind, and knowing that, like almost all of us, I'm more or less happy with the sound but "know" it could be better, just like the greener grass on the other side of my fence, should I

a. stay put and enjoy the music

b. try some sets of different cables - BlueJeans, Morrow, AudioQuest, maybe even Mapleshade - to see what happens (I'd recommend Clear Day, but Paul doesn't make shielded phono cables)

c. Invest in a 10X5 or a Grado Sonata 1 and, if I can't tell a difference, sell it.

d. stay put and enjoy the music

My perception of the prevailing consensus of those members having particularly extensive analog experience is that in general a top notch turntable and tonearm coupled with a merely good cartridge will handily outperform a top notch cartridge coupled with a merely good turntable and tonearm.

But in this particular situation we are not dealing with generalities, we are dealing with a very specific set of circumstances, including cost constraints that appear to preclude a significant upgrade of the turntable/tonearm, at least in the near term. Although I have no specific familiarity with the present Pro-ject turntable, under the circumstances I would ignore general philosophy, and repeat my earlier recommendation of the A-T 150MLX + Blue Jeans LC1 (both of them together, which would cost a total of around $520; you might also need a plain piece of insulated hookup wire for the ground connection).

I used to own the initial version of the Grado Reference Sonata. It was OK, and did nothing that was blatantly wrong, but I strongly suspect based on inputs that have been provided here by particularly knowledgeable members that the 150MLX would be much more of an upgrade. Also, keep in mind that Grados hum in some turntables, due to the lack of shielding in their wood bodies. I have no particular knowledge of the Dynavectors that have been discussed.

If you later see fit to upgrade the turntable, I would not expect that it would be difficult to find a suitable upgrade that would be compatible with the 150MLX. You would just want to avoid tonearms having particularly high effective mass, that are particularly designed with low-compliance low output moving coils in mind.

Finally, if my earlier comments about the 150MLX came across as overly cautionary, that was not my intent. Pretty much everything I said along those lines applies similarly to all of the other cartridges which have been suggested. I was just being thorough in expressing a SLIGHT uncertainty about the tonearm/cartridge matchup, given as I say that I have no specific experience with either product, and I am therefore not in a position to vouch for the combo with 100.00% certainty.

Agreed with Zd542,
There is a significant sonic difference upgrading to a 10x5, more so upgrading to a 20XL, even more so upgrading to a Virtuoso, especially with not so expensive ancillary equipment.

Junk in, junk out! Your entire system is pretty good and you will have to spend around $2,500 - $3,000 to get a much better table. The 5.1 may be a limiting factor if you want to try a Lyra Kleos but for sub $1,000 is good enough.

You all have been tremendously helpful. I'm mulling the AT-150 or the Dyn 10x5 or the Ortofon Black. I knew the 5.1SE wouldn't be a Lyra or Koetsu-caliber table, but I wasn't really looking for that initially.

I don't know whether i'll be going server or vinyl ultimately, though I suspect the latter if only because I still use my Smith-Corona manual typewriter that I've had for 20 years.

In particular, thank you to Kiko and Al for their thoughtful and patient advice.
