First of all, apologize if this topic has already been discussed in the forum; I’ve been looking and reading enough, and I haven’t found any clear reviews.
The fact is that, after my journey to finally ProAc SM100 and Tablette 10 SE monitors on two different secondary systems, I started updating our main system, originally with Exposure 3010S2 (integrated + power amp) bi-amping some high-level Spanish floorstanders. The problem was with the speakers, which, given the dimensions of the room (about 35 square meters and about 130 cubic meters), lacked the proper lows and the sound remained very bright. So, and in love with ProAc, I decided to swap them for a new brand unit of K6, thinking, from the dealer’s advice, they would make good crumbs with the Exposures. But then, the Exposure amplification did not perform properly with the K6’s ribbon tweeters, and the sound went hot and soft, with hardly any treble extension.
Consequently, I decided to update the amplification, and, after extensive search and test, I opted for a new brand unit of the already few in stock of Supernait 2, which I find excellent with the K6, a married made in heaven, as you usually say out there . And that’s why I’m here.
Beyond background, I have decided to write to the forum in search of experience and knowledge.
It turns out that, despite the excellences of SN2, and that it is already quite, if not fully, run up, at high volume levels, above 90 dB, I perceive a certain trend towards brightness and some congestion in complex tracks.
I started with updating all interconnect wiring, from mid-range to high-end, but I have not yet installed it, and with quality insulation, which I have not been able to install yet. But I also think on the amplification upgrade path, maturing the addition of the HI-CAP PSU and bi-amping the speakers with the addition of a NAP250 DR unit, but I am assailed by some doubts:
Will this bi-amplification path using the SN2 with the HI-CAP PSU and NAP250 DR be viable, and above all, will it be the improvement at the end of the journey…?
Since there is no way of adjusting the level of the two amplifiers independently, and Naim does not provide information about the SN2’s power stage gain level, is it possible that any small difference in gain between the NAP250 DR (+29 dB gain level) and the power stage of the Supernait 2 is translated into an incorrect tonal balance…?
In any case, what would be the connection scheme to properly bi-amplify the speakers with the configuration mentioned above, would I to make the connections as described in section 6.3 of the manual for SUPERNAIT 2 with Hi-Cap Power Supply and NAP 200 Power Amplifier , (in this case NAP250 DR, although both NAPs offer the same gain level) or should I make them as described in section 6.1 of the manual for SUPERNAIT 2 with Hi-Cap Power Supply and additionally as described in section 6.2 for SUPERNAIT 2 with additional NAP200 to take advantage of the Supernait 2’s bi-amp output…?
I would greatly appreciate any experience and knowledge of who might have tried this path with a similar configuration, and, in general, any contribution on the topic.
Apologies for the extension, thanking you in advance, receive a cordial greeting,
