Me, myself, I'm always looking for a bargain, so I never, ever buy new.  I always purchase pre-owned.  For the past over 20 years, whenever I was in need of all things high end audio, I usually am able to find great deals at one of the following websites (primarily):  Audiogon, HiFi Shark, US Audiomart and Ebay.  On occasion, I'll fid a great deal at an Audio dealer, even if it's in another state.       

In the Phoenix area, LMC Entertainment in Scottsdale or Tempe.  Good guys there. I bought my MA352 from them and they gave me a reasonable trade-in on my older MA6900.  I also purchased a used MAC MCD350 SACD/CD player from them.

In Chicago, Saturday Audio Exchange.

Very friendly, knowledgeable staff. Limited hours go to their website for more:
