Silly turntable question


(The question, not the TT!)

I'm assembling a turntable setup, slowly over time.
At this point I have an SP-10 with the factory
obsidian plinth/cover. I have a new SME-V for it
that I bought about 6 years ago (I did say slowly). It's
not even set up yet, let alone having been listened to.

Now, I've gotten the idea in my head that I want a 12-inch
arm instead, the SME-312. THAT would mean selling the
obsidian plinth and buying something custom, as well as
buying the new arm.

I'm willing to admit that I must surely have some mental
quirk to want this change, untested.

Even so, I humbly ask you, what could I expect soundwise
if I followed through with this proposed upgrade ?
Subtle improvements ? How subtle ?
Or, should I just be happy with what I have ?

Speakers are DIY custom built, amps are Brystons,
listening room is way too small.

"Do you think I'll be happy ?" What a question.

Seems silly to me to have something and not even try it before you get something else. It will at least give you more perspective on the differences between the two. I suppose if your SME V in still in the box and has never been used it may be worth more when you sell it.
My apologies to Elizabeth. My reading skills are obviously going south.
Mea culpa.(Although I admit to having projects, like getting my old Quads
restored, that have just languished). And Doug, thank you for the kind
correction.
Dear Noslepemus: IMHO you can't help you with this kind of thread when you did not even set up yet the SP10!!!!. Why to worry about the tonearm right now?

I agree with Aigenga: " make the TT/tonearm/cartridge set up " and listening to it. Then fine tune what is that set up and listen.

After that you could think on some chages down there: from TT plinth, cartridge, tonearm, phono stage and the like.

Btw, IMHO the best plinth in any SP10 is NO PLINTH at all. You could make an Agon research about and when you will be ready to take a plinth decision then you can take that " road " or whatever you want, just an opinion.

Regards and enjoy the music,

You are absolutely correct, your question is silly. Anything you actually implement would be an improvement over the silence emanating from your current rig.

improving the phono stage, cartridge, or your skill setting things up, would probably make more of a difference than going to a longer tonearm.
First, thank you folks very much for your comments !
I'm the first to laugh at myself about this, I have other
unfinished projects at home on par with this. I seem to be
pretty good at starting projects but not as good at
finishing.

I have an old Clearaudio Accurate cart (12g, 15cu) that
"should" resonate at 8.06Hz on the 14g SME-312s, and at
8.57Hz on the 11g SME-V. So that would indicate I probably
need a new cart too if I bought the 312s. I could of course
just try it on the -V and not spend any money. Don't know
if this considered a match made in heaven or not.

If I did not use the -V, I could probably get a bit more
on a sale/trade-in, this is true.

Some of you have given me powerful arguements for further
thinking...........;)
