Wrinkles Posted August 29, 2010 Share Posted August 29, 2010 I picked up a used D60 amplifier. I found it to be kinda bright and very solid state sounding. Are all the earlier D series amplifiers (D45, D60, D75) the same way? Is this due to the op amp or transistor technology at the time?

djk Posted August 29, 2010 Share Posted August 29, 2010 That's pretty much the way they sounded. Newer versions had a different opamp and sounded better, but the older ones cannot be upgraded without a lot of blood, sweat, toil, and tears. The D150/D150A and DC300A of the same vintage were the same, but even more so (if you get my drift). I usually describe the D150/D150A using terms like 'broken glass'.

Moderators dtel Posted August 29, 2010 Moderators Share Posted August 29, 2010 I don't know, I use the D-75's, but I haven't tried anything else. Partly because i need 4 channels and that makes it a little harder to just try another amp, plus there connected with XLR connectors. They are really low distortion and built tough, I just have no experience comparing them to another amp. Quote Link to comment Share on other sites More sharing options...
Wrinkles Posted August 29, 2010 Author Share Posted August 29, 2010 My Crown PSA-2 sounds so much better on the upper frequencies. I'll try the D60 amp on the LaScala bass cabinets once I get the XLR to RCA adapters in from Monoprice. I contemplated replacing the input caps, but it would be too much trouble. Thanks for the input. Quote Link to comment Share on other sites More sharing options...
djk Posted August 30, 2010 Share Posted August 30, 2010 The PSA-2 is still one of the best Crown amplifiers. Newer D75 have a better opamp in them, they also switched to class AB (earlier ones were class AB+B, no bias in the output stage). Quote Link to comment Share on other sites More sharing options...
HarryO Posted August 30, 2010 Share Posted August 30, 2010 Mark Deneen did a nice upgrade mod on the 60 IIRC. It might have been the 75 but not 100% sure my memory is intact. Check some posts here about it. It sounded interesting. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted August 30, 2010 Share Posted August 30, 2010 [:$] I haven't heard it yet. Next week, I'll be getting Mike Lindseys modded Lascalas. I'm going to pair those speakers with the Duke and an Anthem TLP-1. I've been aquiring pieces for a while and the speakers are the last piece of the puzzle. Ashamed to admit that I'm a SS man at heart. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted August 30, 2010 Moderators Share Posted August 30, 2010 I feel a little better, ever since reading the first part of this thread I have been wondering, I like the sound....but ? If I ever get the chance to have two amps the same or a 4-5 channel amp I want tot try it out. Quote Link to comment Share on other sites More sharing options...
Myhamish Posted September 2, 2010 Share Posted September 2, 2010 Consider yourself lucky to find one. It could be older than you. Back in the early days, Crowns did double duty - for home applications with the DC 150 pre-amps and professional sound reinforcement applications. DC300s and DC300As served as the yeoman power amps for many concerts that we attended as kids. Many D60s and D75s were the bastion power amps for broadcast monitor applications. It's a testament to the robust 'built in the USA' quality that they're still around today. We grew up with the stuff. How many 1970 cars are still on the road today? These amps deserve a modicum of respect in their senior years. In regards to your D60, if taken care of (caps & etc.), it should be around for another 50 years. Enjoy. Slainte.
