So what would you recommend for my next upgrade?

Dancub, nice to see you are open to new ideas.

I recommend Herbie's Audio Lab.

He makes all kinds of isolation devices for everything in the system. Even makes a very nice TT mat; I use one and noticed better dynamics and a more focused sound. (He will also offer advice).

I use Big Tall Tenderfeet under every component. Not expensive for the many benefits they provide. You should defintiely use an isolation footer under the CDP and preamp. Also for an integrated in your case.

And there's nothing wrong with Blue Jeans cable. Sounds better than many expensive ICs. They're cheap so use them until you're ready to upgrade.

With all that vinyl, getting a record cleaning machine should be a priority. Next.. a tube phono pre would be nice in your system.

At the risk of being cast out for Blasphemy...

Have you considered an Analog to Digital Convertor, such as the Ayre QA9?

If you're more adventurous, and want to remain in the analog world, another upgrade to consider would be a quality reel-to-reel. To paraphrase, vinyl is nice, but nothing else quite sounds like tape...

Hope that helps.

Gslone - got a vac cleaner so am starting to use.

Courant - I do have a couple ADCs but not sure what to do with them. The records I want to transcribe are, so far, limited. Don't know what if anything else they buy me.....?

No one's suggested an alternative to my NAD phono pre yet ... ?

I moved into a dedicated audio room ~ 1 year ago. Made my own sound panels using supplies from ATS Acoustics. I also tune by ear, as I agree, more fun. It is an ongoing process. Seems I have a tendency to over treat then remove treatment until I get it right.

No problem with the Blue Jeans. Based from what I have heard from others a good place to start. Cable upgrades and other tweeks can be added after you have dealt with room treatment and speaker placement.

I am hesitant to recommend a phono pre as I have only owned 3 recent ones. A Jolida JD-9, NAD PP3i, and now a Lounge. The Jolida was the best of the three and very flexible. I would look into Music Direct and Needle Doctor online. They have several models available. I think you would benefit from more gain than the NAD provides (36dB i believe). I also have the Bluepoint. The Bluepoint outputs 2.5 mV which is at the low end of the HOMC/MM range. Sumiko recommends a capacitive loading of 50 pF at 47K resistance.

Good luck on development of your listening room.
