2016年2月13日 · Shame to see quality control or design issues in a brand like NAD. Even if the digital inputs were not broken, the performance of the DAC fails to even match a half decent $9 phone dongle. So despite great feature set, NAD needs to go back to the drawing board and clean up its implementation. Needless to say I can't recommend the NAD C658.-----

2024年3月29日 · However the NAD C658 is very nice indeed, and huge upgrade on SBT and separate DAC and with the subwoofer out and adjustable crossover, I've got it sounding very nice. Yes, there is the occasional room effect and audible bass hump, but will gladly live with that to retain the musicality and soul of the music v the sterile, flat Dirac adjusted ...

2021年2月21日 · We are adding a new addition onto the house, and I decided to dedicate some space to 2 channel music listening. After consideration, I have acquired the following hardware: NAD C658 streaming DAC/pre-amp NAD C298 amp B&W Matrix 805 mains B&W Matrix ASW800 subwoofer Rocket33 cables Audioquest...

After a detailed investigation, our engineers came to the conclusion that the C 658 sub voltage is correct and operating as expected. It may help to increase the input gain on the subwoofer itself. I would also recommend looking into how the subwoofer is connected to the C 658.

2020年3月17日 · Nad C658 uses a Linkwitz-Riley filter design for their crossovers which are very similar to Butterworth. The main difference is that Butterworth crossovers have a 3dB bump at the crossover point, whereas Linkwitz-Riley crossovers are flat.

2021年3月6日 · Others have recommended adding a MiniDSP 2x4 to the chain, between the sub out of the C 658 and the input of the sub, in order to increase the volume of the sub, but that is one more box (not to mention $200). Unfortunately the C 658 does not have a volume adjustment for the sub and the default (and only option) is way too low on many units.

2021年2月12日 · Is there any other components on the market that do all that the NAD 658 does? Streamer DIRAC Ethernet Wi-fi Bluetooth version Two-way aptX HD Inputs Optical, coaxial, USB, phono, RCA inputs Outputs Unbalanced and balanced RCA outputs Hi-res 32-bit/192kHz

2020年3月17日 · In light of the above, I purchased a (new) NAD C 658 a couple of weeks ago and everything seems just fine, particularly no popping. (Many of the complaints that I saw that referred to popping sounds said that the sounds were when no music was playing. It's hard to see what that would have to do with loss of digital signal lock.)
