I am looking to get pair of these for biamping my salon 2's...
What you guys think..Salon 2's are hard to drive

What are you driving the Salon 2's with now?

I was using ati ncore amps in biamp...
Just received my xpa gen3...tried that and liked it over ncore amp with salon 2's.
Hence thinking of DR2's for front..

WHat are you using as a crossover in your 'biamp' setup? Dependig on several factors, going to an Active LLXO might gain you as much as 3db 'apparent' power. What makes you think the Salon 2 are a difficult load? Stereophile tends to disagree. www.stereophile.com/content/revel-ultima-salon2-loudspeaker-measurementsPhase / impedance data is not too bad, at all, indicating a modest load for any reasonable amp. |

I am only doing passive biamp..
Or should consider two DR1's with no biamp?

I am going to try the dr-1s...the XPRs were great as well.... I am very interested in your opinions when you receive DR1 The sound of the dr-3 was very clean but ultimately I decided I am a monoblock guy for front stage! |

I wish I had the room for monoblocks ... Even with the XPA-DR3 I'd have to cope with a second chassis for all the other channels which will be ... interesting in my living room ...

Given the seperation is in the source, monobloocks have only one potential advantage. Short speaker wires. Other than that?
Mostly a red-herring.
You CAN build an awful lot of power into a single chassis but even than, the most powerful will be back breakingly heavy. Thus 'D' amps with switchers.

By the way, in line with the question of monoblocks versus multi-channel amplifiers: As far as I know, UL and FCC rules only call for EMI testing of products with regard to signals outside the product, but not inside. So for a monoblock, it would presumably be reasonably safe from any induced signal from another monoblock, even if placed on top of each other. But what about the amplifier modules within a single chassis? They could all be very separate in terms of the over-all amplifier design, fully differential, etc., etc. Is there some worry and/or engineering which has to be done to prevent EMI interference between the amplifier modules within a multi-channel amplifier? Just curious. Mostly I'd assumed that "channel separation" referred to more prosaic ways of inducing signals between amplifier modules housed in a common enclosure ...

I just put a DR-3 on order to consolidate my amps down from 3 x XPA-1s from my fronts and center to one chassis as I'm going to start moving more due to the military. If the DR-3 is as good as my XPA-1s, that is fine by me. |

I figured I'd just wrap some aluminum foil around all the wires in my new amp and be done with it.  This RFI stuff is nothing close to my area of expertise (water supply engineering) so it's close to Greek for me. |

Yep, I look forward to seeing what happens. My DR-3 is 10-14 days from shipping, after which I'll put my XPA-1s back up for sale...

Is DR2 better than regular X amp? Did anyone compare the two?

Post by 2001passvar on Feb 1, 2018 16:11:53 GMT -5
Don't know, but I just got notification that my DR2 order is complete, so I'll be getting that amp in a few days and I've already got a XPA3 Gen 3, so I'll be able to compare them soon.
