Well, it has been 3 hard days of wires and testings and, I really have mixed feelings. As a very short summary I find it very difficult to determine a clear winner.
In general the experience is possitive so sorry if the comments may focus on the problematic areas more than on the possitive.
Cinema - Cinema experience seem more impressive and immersive specially using the 3D DSP modes. However, the sound is also a bit "artificial" and it could end up creating acoustic fatigue. I was watching an action movie on Monday and I had to put the volume all the way down towards the end because I could not bear it any longer. (I had the "adventure" DSP mode on).
Features - Has many more features than the old Arcam however, many that I will probably not use.
Genera sound - The sound in general tends to be a bit more harsh. I have the feeling that everything sounds more powerful but less detailed.
Music - Sounds more powerfull and dense but the detail and separation is not as good. The overall experience is acceptable but it definetly does not get the "WOW" factor. I used to think that the Arcam played quite well here and did good job in extracting the detail and specially avoiding artificial sound. This point regarding music is very important for me son unless I see changes in few days or find a way to overcome the issues, it could end up being determining.
Any similar experiences? Could it be that the Dali Ikon and Yamaha are not a good match? Could it be that the Yamaha still needs further run-in time (I am not a great believer of this for receivers to be honest)?
I only have 2 more days of trial before the return time expires. I see a lot of pottential in this receiver but just a few issues that make it hard to make a final decission. Any comments will be appreciated.
