classe twenty five and classe fifteen

I would say no, as the DR25 just had enough current for the 3.6's when I had them.

The low impedance value explains the CS3.6's need for the iron-fisted Mark Levinson No.23.5 to provide control in the bass; the CS3.6 would appear to be current-hungry.

So I got a pair of classe 25z I don’t know if they’re dr or not. I also have no idea what I’m looking at inside as the inside looks way different. Any classe aficionados on here that could look at the pictures and say? One seems to have updated output boards attached. And the other seems to have the original boards on the outputs but they added 4 more filter caps to the filter board

Open the cover and look at the circuit boards.  The main board should say "designed by Glen Grue". if it is, its the 25.  The DR25 was designed by David Reish.  Glen Grue pushed him out when he took over the company.

just look at front panel...either the earlier DR-25 or later Twenty Five

Classe 15 outputs 550wpc into 2 ohm loads.

The Classé 15 and 25 are much better than the DR equivalents.

My Krell KSA 200s is much better than my Classe 15.

My Krell KSA 250 is not as good as my KSA 200s.

 The DR 8 and DR 9 both sound better bridged.

This is the way!
