which Speaker with which amp?

Frankly………….all these are pretty decent entry level speakers if you are going the branded path. My suggestion would be to listen and decide yourself. Trust your own ears because all these will be voiced differently. In fact voicing will be the only difference between all three. They are all entry level audiophile speakers with similar parts / compromises built into them. If you want better bang for the buck and a taste of high-end sound around similar pricing try Lyrita-audio towers or Acoustic portrait MS 301. They are in a different league.
Amps..again both are good choices. Voiced slightly different. CA will be slightly laid back and NAD is an all-rounder. Warm with a bit more forwardness than CA. You need to listen and decide.

hi there,

Try the Monitor audio bronze 4 with the Marantz pm 4001 or
the Nad c 320bee.

Where can one demo Marantz amps in Mumbai?

listening to different combinations can be very difficult if not impossible. unless sold by the same dealer.

Dali + NAD C352 would be a good combination. FYI, the NAD c352 won the Gold Award from Hi-Fi Choice. I don't care the award...but I own this amp and luv it. They go will all types of music . It is very neutral and musical. Just replace the stock power cord. If you opt the MAs, then go fo the Silvers.

Dear Manags,

Try and get in touch with Sushil Anand at Mumbai for the
Monitor Audio B4 and see if he can arrange a Marantz amp for demo.

Regards
Jay
