We do things in life based on our experiences. And we all have different experiences. So we will make different decisions/choices.
But let's put it this way. If you were Bill Gates and you offered me a FREE CX-A5200 or a FREE AV8805, I would choose the CX-A5200.
Actually, I would ask Bill Gates for two CX-A5200.
If I thought the AV8805 sounds 1% better and is as reliable as the CX-A5200, I would have gotten the AV8805 for myself.
Coming from a Denon AVP-A1HDCI, you'd think I'd be getting the Marantz. But I didn't.
In my experience, just because something costs a lot more doesn't mean they will sound any better or is better made and will last longer.
Like I said, we all take different paths based on our experiences in life. And at least for now, the path for me is Yamaha. Or ATI.
I have the Yamaha CX-A5100, Yamaha MX-A5000, and ATI AT2005 in my system.
Now if you are thinking of spending $4K on a Pre-pro, Monolith is coming out with the HTP-1 (derived from the $10,000 DataSat LS10).
Of course, since you already have the ATI amp, you might want to wait and see what ATI does with their ATP-16 pre-pro (also from the DataSat LS10, which is owned by ATI).
