Have to respond here, the NAD C 658 sounds freaking amazing with the right amp and cabling.
What amplifier, and cabling are you using with the NAD C658 if you are using it with a Marantz receiver as an amplifier you will not be happy, the Marantz receivers are okay at best we have installed them before not that good in terms of sound quality compared to the higher end receivers from Arcam, Audio Control, etc.
We paired our C 658 with the Nuprime STA 9 which is a $699 120 watt stereo amp $1,399.00 as a 290 watt mono block set and the sound quality was outstanding.
We did a recent shoot out of the NAD M10 which is a 100 watt Hypex amplifer with the same features as the C 658 vs the Naim Atom and the Atom was much warmer and fuller.
If your dealer was using the C658 with the matching 80 watt Nad Hypex amplifier and or the wrong cabling that is the reason why you didn't like the sound. The Nuprime amplifiers are a hybrid Class A/D technology and are designed to emulate the sound and musicality of a tube amplifier
this combination was so remarkable that we just ordered a second STA 9 to run the mono bridge to create this package of 290 watt monos with the Blue sound streaming dac.
We compared the Nuprime STA 9/NAD C658 to a Hegel H190 and the Nuprime/Nad pair was warmer, punchier, nearly as detailed with a huge soundstage.
You can give us a call and we can assist you with your setup of the C658 it is remarkable piece when setup right.
