Your post gives me confidence. Which Amp gives better music- Norge or Marantz? Have you placed the 2605 aligned to 15' or 12' wall? What is the distance between the speakers on the rear and the sides? Are you using a sub? If so, please tell me about its placement too. Also, please suggest some good interconnects.
As I said earlier, I like the sound signatures of both Norge and Marantz.
Marantz PM6006 and Sonodyne 2605v2 combo is warm and cool, cosy and comfortable, sweet and lively, but not for partying. Lows are neutral, mids may be just slightly forward, highs are neutral, an overall balance.
Norge 1000 Gold and Sonodyne 2605v2 combo is the same as above, but with slightly forward highs, with the added advantage of partying in home because of the slightly forward highs and also more rms power.
Though Norge audio specify that Norge 1000 Gold has 92 watts rms per channel, at 8 ohms, but I will say that it is 92 watts rms at 1 khz, but not for the entire spectrum. For the entire spectrum of 20 to 20,000 hz the power of Norge 1000 Gold will be about 60 watts rms per channel at 8 ohms. Whereas Marantz PM6006 has 45 watts rms per channel, at 8 ohms, in the entire spectrum of 20 to 20,000 hz.
For the same music and same volume, if Norge volume pot goes up to 9 O' clock position, then Marantz volume pot has to go upto 10 O' clock position. Powerwise, Norge has more power.
2605 has been aligned to the 12' wall.
Since the speakers are front ported, there is not much distance between the rear wall and speakers, hardly 12", and the speakers are about 5 feet away from each other. No sub, as said earlier, it is difficult to perfectly integrate the subs and front speakers, so I don't want to waste time in that.
For interconnects, I use Prolink cables, and for speaker wire, I use copper speaker wire no. 23/36, which is roughly 0.7 sq mm..
