Life could be so easy if there wasn’t always something to improve.
Actually, I’m quite happy with my systhem, but… I fought bravely against the upgrade virus, and relapsed.
It has become a small step. I replaced my NAP 300 with a NAP 300 DR. Now she is on power for three days and is warming up.
Actually, I want to sell the “non-DR” NAP300, but it’s still there and I’m wondering if I shouldn’t use it for biamping or build a second power supply to the 300. A dealer from Hamburg wrote: “We also switched on the extra fat & fine BiTurbo again in the demo, terrific tuning, clearly better than NAP500 (nonDR), close to NAP500DR.”
Since the DR update does not affect the power supply, I have two identical power supplies at the moment and at least technically this should be possible, or am I wrong?
We tried using two power supplies on a NAP500 at the factory many years back. It did some interesting things. The sound seemed to grow in size and space but at the same time it was all less of a whole and picked apart, which detracted from the music. So, overall not a success unless you favoured “hifi” effects over music. I recall that Roy speculated that perhaps the unused channel of each PS was contributing “parasitic effects” (no idea, so please don’t ask)…
Excellent advice from HH. Just to add, bi-amping has been covered many times here on the forum, not something that is part of Naim ethos; search is your friend.
It can an I have seen it just plug one in one side and one in the other , turn them both on at the same time. It’s that easy , you could even combine both windings and caps , that’s a bigger supply than the 500.
I tried it out today.
The NAP 300 DR with two power supply units.
The result:
I didn’t faint with enthusiasm.
I would say a little more punch in the bass, but also somehow not as precise in the vocals. Just like Richard said, actually.
It was also a bit difficult because I was alone at home and a lot of time had passed due to the re-plugging. More tests would be necessary to make it more conclusive. Perhaps I should have left both power supply units connected to the 300 DR for several days.
I also wouldn’t know how to integrate the seventh box properly into my rack.
I think you’d get better results doing fully 2 NAP300s with vertical biamping (if speakers support it) rather than either a single 300 with two power supplies or two 300s horizontally biamped.
Yes, that could be, but then I would have two more boxes. But they should also be two identical power amplifiers.
My ‘old’ power amplifier has no DR and the new one fortunately now has DR.
In terms of price, we are then at 2/3 of a NAP 500, both new and used, which would probably be the better choice.
