Well that may be the case in the US but in the UK, Denon's premium product has been upwards of �5k for some years ... current AV preamp just under �7k.
That's more than G68 or G61R + HD621.
True enough 800 series is more expensive but my point is that many folk here are STILL using products such as 568, or indeed 565 and these units are in the main very reliable and offer fantastic performance for their age. Indeed 568.2mm can be used with HD621 to provide a very effective solution for modern HD audio ...can you think of ANY other AV product from that era offering this?
