I’ve owned the JBL 530 for a couple years now. I also got to demo a Marantz NR1508 for a few days as well. I thought it sounded better than the NAD C328.

I just demoed the NAD C328 with the KEF LS50, Klipsch RP-150M and JBL Studio 530. I really wanted like this piece because it had all the features I was looking for use in my bedroom 2channel system. However the sound quality was just not there. Bass is lacking and the midrange seems thin. I can see why they included a bass boost eq. It sounded best paired with the JBL’s but I don’t this amp delivers the full potential of any of these speakers. I also have a Cambridge CXA60 on hand for comparison which is in a different league to the NAD. The sound from the Cambridge is richer and more full bodied.

I just spent a couple weeks with the Emotiva A-300 and my RP28F’s. Compared to my Denon AVR-X4300 the Emotiva had a much cleaner sound. However that clarity came at the expense of leaner bass and spitty sibilants. Needless to say I was disappointed given Emotiva’s reputation among the online forums. The Denon was so much warmer sounding. It’s a surprising result because I had went in into purchasing the Emotiva thinking dedicated amplifiers should be superior receivers. So for now the Emotiva is going back and I’m sticking with the Denon to drive my RP28F’s.

Thanks! The supplied spikes were so blunt. Not sharp at all.

Does anyone know what type of bolt the threaded sockets accept beneath the base plate where you install spikes on the RP28F?
