Yes agreed the new MA Gold 5g model is very smooth (too smooth sometimes) and the highs is sooo smooth and I feel it could use a bit more resolution.
What kind of electronics and cables are you using?
My Gold 200 5g are being driven by a Cary Audio SA 200.2 ES solid state power amp and a Classe CP 800 preamp (soon to be replaced possibly by a tube pre or a hybrid tube design pre such as the PS Audio BHK pre) and a Cary Audio CD 306 SACD player/DAC served as a digital front end source component.
For speaker cables and XLR analog audio interconnects I’m using Cardas Clear Reflection cables. For AC power cables I use 2 Shunyata Research Delta V2 power cords and a Transparent Reference Powerlink MM1 power cord (older model and soon to be replaced by a Shunyata Delta V2). I have the Shunyata PS8 AC power line distributor with the Venom Defender plugged on the PS8, and a Shunyata Delta V2 C19 power cord connects the PS8 to the wall outlet.
I highly recommend the Cardas Clear Reflection speaker cables and analog interconnects. And for AC power cables and AC power products I recommend Shunyata Research (at least the Delta series or higher).
