what speaker new or used for 5k?

I'm not sure if it would be wiser to replace my amp and pre to match the Mozarts? or replace the Mozarts to a speaker that matches my amp and pre amp better? I don't think id have any problem selling any of the equipment. I do think the a21 is a warmer sounding amp and that may be the reason the Mozarts don't sound right. not sure if id go with a class d amp, I do have a friend who has a pure class a amp I could borrow and see what that does for the Mozarts.

Jughead, Marqmike,

Out of curiosity, and a need to save a bit of cash, I sold a nice First Watt M2 amp, and ordered a Class D Audio CDA 254 amp, in a kit. You can have them build it, or they have complete amps ready to sell.

Anyway, I built the first one, and I was shocked at the quality of sound coming out of my custom-built Tannoy HPD 315 loudspeakers.

I was getting the best bass response I'd heard from my 12" Dual Concentric speakers, with beautiful mids and highs as well. It compared very favorably with my SET 300B amp, but with more power.

I built another one, and ran two amps bridged into mono, making 500 Watts into 8 Ohms. It sounded superb, but an old multi channel amp I was using for center and surrounds went bad, so I converted one of the amps to three channel, just had to add another amp module and input and speaker terminals, with the one unit, there's 125 Wpc for the surrounds, and 500 Watts to the center channel.

Multi-channel music, and tv watching has never sounded this good before.

Along with Marqmike, I recommend you give them a try. I am living very happily with Class D, and the complete kit is only $430, very high quality parts, and made in the USA. It costs an additional $100, I believe, to have them build it for you.

It's something to think about. I think you'd be surprised, I know I sure was.

Best of luck,
Dan

I had a Parasound A21 and replaced it with a Jeff Rowland 525 Class D amp. The 525 has much better front to back place within the soundstage and a wider/deeper soundstage. Instruments have the proper size and much better tonality compared to the A21. It may not be for you, but all Class D amps don't sound the same.

What companies do in home trial for class d amps? I'm fine with trying it as long as I can return it if it doesn't meet my standards.

What kind of floor is under your speakers? Are they on an upper level? Are the floors suspended plywood? if you jump up and down does anything in the room pick up vibrations?

if so the problem may be inherent in your room/floor. Some speakers may isolate from floor interactions better than others. One cheap solution worth trying is to put teh speakers on isolation pads. I use Auralex subdudes under my OHMs on my second floor where this is a problem as it is with much modern constructed houses. A problem for Hifis and speakers but the give is good for avoiding structural damage in earthquakes, etc. Subdudes, if practical for use under speakers like yours, run about $50-$60 each on Amazon.

BTW when I use teh same OHM speakers in my basement on solid concrete foundation with thin carpet and padding, nothing else is needed. I can jump up and down all day down there and not much will vibrate. If I really turn things up, the walls and doors might just a bit, enough for the key I store above teh door frame to eventually fall to teh floor. Nothing particularly audible though. The same speakers off teh same gear are able to shine right through becasue there is little or no vibration transmitted to teh floor.

You might want to try some kind of isolating platform under teh speakers if you think you have this problem first before investing megabucks in other speakers that may solve teh problem in a similar manner out of teh box.

Just somefood for thought.
