Advice on Equipment Upgrade

Mattmiller, Did you hear the digital system in the current room?

We are always trying to keep our tonearm resonance between 8 and 12 Hz, is it possible your room is getting to this area, or the tonearm/cartridge resonance is out of this area? You can check it on the vinylengine database.

I normally would not mention the next suggestion, but you may need to check into a room correction devise. If my room changed a lot and I was going to try to use the same equipment in each situation, I would at least consider it.

Good Luck!

Assuming you run unbalanced ICs from pre-amp (which does not appear to support balanced connection) to the Mc, the low 20K input impedance of the Mc amp relative to the tube pre-amp output impedance could be an issue leading to softer less dynamic sound overall including mid bass in particular and more distortion. I would want 50-60kohm input impedance on the amp minimum with most tube pre-amps to help assure best results. I'd be willing to bet addressing this would make a noticeable difference.

Getting the sub to blend in well without any negative effects in a small room like that would also be a challenge generally I would think. I would get the sound right without the sub first then see what can be done to add the sub in a manner that is purely positive.

WHat kind of music do you find the sub helps with? THat is a very small room that might make adding a sub in effectively with no ill effects on the mid bass a particularly hard challenge I am thinking. That might help account for the dullness in that range as you describe.

Hey I see a lot is made of the room size. To clarify, the room is off a tiled entry way so the space is really larger. The room is small but opens up right away to a total size of 14'wide x 16' deep. Still not a great scenario I know.Also, The matter of the preamp out (2800) into the Mac Amp (unbal-20,000) is a concern.(more on that in a few days)I have a 4.0mv MM cart. I listen to Classic Rock and 50's 60's jazz. Music that is Simple sounds Awesome!Bass is deep and tight in the lower octaves(below 30hz).Very articulate and smooth ,velvet vocals,Sax,with very real sounding cymbals bells ect..BUT when I put on something with Balls like Billy Cobham -Spectrum Atlantic SD7268, it dosen't have that EDGE or driving Attack of the percussion that i have heard from this record. Do I really have to talk about Digital? Ok....I had this very system hooked up with a Mc201 and a Nordost Valkyrja Bal IC Directly to the MC352. WOW! is all I can say. The sound is Celing to the floor in dynamic range and Quick like lightning, Sure the 201 isnt the best sounding CD player.Compromise,compromise,but having control of the volume without a preamp added some real grunt into the system I had not heard while using a preamp,On Talking Heads Speaking in Tongues-Burning down the house sounds like my speakers are playing Instruments! Instead of boxes playing beautiful music.A lot of Impact and dynamics, very synergistic.Thanks to my brother I'm going to bring in a expensive McIntosh Tube Preamp with Tube Phono stage and do some listening over the weekend, I'll post again soon.

Everyone should be able to click on the SYSTEM button next to my name in this thread to see Pictures!! let me know if you can't.

Definitely worth your time to try the Mac preamp. Hopefully you're talking about a newer one, as it would be a perfect match for the 352. Also, here's some additional info I found. Prima Luna power amps have an input impedance of 100k, which results in a ratio of 35.7 with their preamps. Your MCD 201 directly to the 352 results in a ratio of 33.3. The Prima Luna preamp to the 352 ratio is 7.1.

The combination I had in the past was a tube preamp at 5k output hooked to a solid state amp with a 25k input, just no dynamics and dull, and this amp sounded great with a different preamp, very dynamic. Then I changed to an amp with a 100k input for the tube preamp, and even with less power, but sounded so much better, finally came alive.
