How good is the Marantz SA-7S1?

Well I pulled the trigger on the used one that was being sold on Audiogon. I should have it either Tuesday or Wednesday of next week. I will give my own impressions of the Marantz as soon as they are formed. Bob

I was wondering how long does it take for these units to break-in?

I would be going from an excellent Bluenote Stibbert 2007 with additional Sound Fusion suspension to the Marantz. Has anyone had the privilidge of comparing these fine players? Bob

I am wondering how power cord sensitive is the Marantz? Does the power cord make a huge difference on this machine?

I have the Sa-7 now and it is a very good player. I must say that it sometimes sounds a bit flat compared to the Bluenote. The Bluenote can sound more live in the room than the Marantz. What the Marantz has going for it is a bit more tonally complete presentation and has a bit better resolution. I sometimes wonder if it is a bit on the warm side of neutral. The Marantz seems to have a more mid-hall to rear hall presentation. With the Bluenote, I am upfront and it can sound so good but without the ultimate resolution of the Marantz. It really is a difficult decision picking between the two players. It is maddening because in a perfect world I want the best of both machines.

Waltersalas,
this is a very interesting question that you posed. I have the Marantz for sale here but I may be pulling the ad tomorrow. I felt that my system was good with refurbished Apogee Scintillas and a pair of Conrad Johnson Evolution 2000's with the ASL Flora preamp (alternating with the Supratek Chenin) and the weak link was the speaker cables. Anyway, as I said in an earlier post the Marantz sounded flat compared to the Stibbert even though it was more resolving. My friend Teajay (from Audiogon and author of the reference Dac thread who has a wonderful system) today allowed me to audition his Acoustic Zen speaker cables while he was auditioning some even higher resolving Stealth cables. It is a good thing that he likes the Stealth cables because he isn't getting these back! Anyway, with the new speaker cables the Marantz is a completely different player. While the Bluenote still sounds more front row and a bit more live, the flatness of image that I wrote about before in the Marantz disappeared! The Marantz does not sound distant or remote like I experienced just yesterday. The higher resolution of the Marantz can be stunning. As of tonight, the Marantz seems tranformed as hard as it is to believe. I will listen more over the weekend but if forced to make a decision right now I think that I would keep the Marantz. Tonight the Marantz just made music for the first time.
I think that the reason that one sees a number of these players available on audiogon may be that the systems they were heard in were just not resolving enough for the Marantz's qualities to be heard. It could also be that the players didn't synergize well in those individual's systems. This points out how difficult it is take a components measure without fully exploring all avenues of your own system. I feel quite stunned and hope I didn't lead anyone astray. Bob
