Next Upgrade??

thanks everyone for the input! @mulveling, you have a lot of good infor for me. I've been a rogue guy for 20 years and have had nothing but positive experiences. My goal is ultimately to have an RP-7 and maybe that's a better move than a new cartridge. Like @flatblackroind said, use the one I have till it wears out and then upgrade. It's a nice cartridge and it seems like the distributor always let's you upgrade which leaves that door open for later. 

Upgrading my amps is not super high on my list. My speakers are a fairly easy load so I don't need the extra power the Apollo's would give me. Might go stepwise to darks but am likely to upgrade my TT before that.

This has been really helpful. Thinking maybe preamp before cartridge at this point and then upgrade cartridge in 1k hours. might also do the linear power supply in the meantime. 

Think about good headphones and a proper headphone amp...you'll be amazed at how good that can sound. 

+1 on the Musical Surroundings Linear Power Supply. An amazing duo!

OK, Miller, here is one for you, IF you have 
bookshelves or other surfaces that are subject
to vibrating when you play music...

I busted an overhead flourescent light cover on the way home
from Home Depot, one of my favorite audio stores.
Instead of throwing it away, I cut it and placed it underneath books
on a bookcase, and cds on some shelves.  The smooth side is
placed down on the surface, and the "rough" side up, in contact
with books/cds.

I'm hearing an improvement!  Right up there with the fo.Q tape,
shungite plates, and Nobsound (knock off) units.
