Marantz ?, sell my Sony?

[callas01]

I pretty much know what I want to do, but let me ask you guys your thoughts.

I have a guy that I sold my entry level Sony STR-DG710 to early this year. He asked to buy my STR-DG920 today for $375-400.

Many of you know that I love the Marantz 5003. I won't have enough cash to get a 5003, but I will be able to buy the 4003 outright, with the money I get from selling the Sony.

The 4003 accepts LPCM, and my BDP can decode all the audio, so I get lossless audio, Plus I gain the very important pre-outs. Marantz's specs are usually right on the money, so I believe it would be true that I would be getting 80 wpc, vs the 40-55 wpc that the Sony is probably giving me.

My question is, do you think I will lose anything by getting the 4003 over the 5003?

The 4003 says it does "HDMI v1.3a Switching/ v1.1 Repeating" please explain to me what that actually means. Does that mean that it doesn't affect 1.3a signals coming in from a BDP to the HDTV, only upscaled analog signals????

Thanks Steve
