Who remembers the Dahlquist DQ-10's?

When it comes to power hungry speakers, what is needed is an amp with high current capability for those ohm swings.   That Parasound has some good current, at 45 amps peak per channel.  It's at the low end of Parasound's line up, however.  Their A21 does 60 amps per channel, which is pretty good.  I owned this amp, and it really has great detail and control and  always sounds effortless.  It's worth a listen, anyway.

Something Emotiva doesn't do is publish the current output of their amps, they really should get with it.  Slew rate, current and output at 2 ohms are all important specs that Emotiva ignores for the XPA-1.  Oh wait, they state that the XPA-1 has a minimum 4 ohm load requirement.  For a mono block, that's embarrassing.  I'd stay away.  It also only goes down to 10 Hz, all of Parasound's Halo amps go down to 5 Hz within rated frequency response.  

mr_g,                                                                         If you lived nearby me in Florida I would lend you some of my vintage amps to try out with your DQ-10's. I have several that might work well: Acoustat TNT, Perreaux 1250B, SpectroAcoustics 500, Bedini 150/150, Sumo Andromeda, BEL 1001, GAS Son of Ampzilla. All of these have sufficient power to drive DQ-10's. It's just a matter of what sonic flavor you'd prefer! I myself recommend matching vintage components with similar vintage gear. Present day new gear is not attractive to me! 

DQ10s.  The first speakers I ever heard that disappeared while playing and the standard I have set for audio speakers ever since.  That was in the mid 70s at Myer Emco in the DC area. I have lusted after them but have never been able to afford the level of amplification they deserve. 

A piece of old trivia.  I'm Phil Schwartz's daughter who was the US importer of Fidelity Research phono cartridges.

Jon, Saul and John Bedini used to exhibit with us at the Jockey Club in Las Vegas in the 70s.  John Bedini used to do hi-end amplifiers.  

One time we were getting feedback/noise, and Saul just grabbed a piece of aluminum foil and placed it on the wires to kill the noise.  Such a low tech fix.

The other part of it was that Jon used to say that his speakers couldn't be blown.  John cranked up Funky Town by Lipps Inc. and cranked it up.  Pop.  We all giggled and popped it back into place.

I, too, was at the Hotel Pennsylvania. And, I too, remember the Dahlquists. ( and, the Shahinian Obelisk's).
They were outstanding.
