Something that concerns me is the impedance match of preamp and power amp, 2.8k to 20k. I've always read that the power amp should be at least 10 times greater than the preamp. I did have a combination in the past that was less than 10 times, and I always thought it sounded dull. Maybe someone else will respond on this.
Advice on Equipment Upgrade
I need some help on what is making my system sound a little dull in the midbass snares toms ect. My system is in a 10.5 x 12 ft room open on the long end. I have Dynaudio Contour 3.0's with a REL B2 sub connected to a McIntosh MC352 solid state amp using a Prima Luna ProLogue Three Tube Preamp. My Source is now a Upgraded REGA P3/24 with a Nagaoka MP200 Cartridge MM. I'm using a Tiny Riaa Phono Input that was incuded on the Prima Luna. My Cables are Nordost SPM skr wire and a upgraded cable for the REL by Signal Cable. And 1 unbalanced 1 meter cable from Morrow audio (MA-3). SO my question is Where are the Drums ??? Do I need a Dynavetor cartridge? Is the Primaluna phono the culpret? Should I invest in a quality Phono Preamp and get a low output MC cartridge? I just want my kick back in my system Its too Warm. Note: I was listing to Digital but I really like the Vinyl sound better for the Jazz and Classic rock.I know these speakers and they can sound much better and its not my amp.Any advice would be greatly appreciated.
thanks

I don't disagree with any of the other comments, however I still think the pre/power impedance match is less than what is considered to be an acceptable minimum. Take a look at this thread, especially the first response by Almarg. http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1341955108&openfrom&1&4#1 |
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. |
