A Graham Slee Power Amplifier?
Most people know me for Phono Preamps and Headphone Amps and maybe a few Interconnects, but as for the rest of the kit: Power Amps, Line Preamps etc, most people could think its not my area... However, many years ago, power amps and line amps were just about all I did professionally. The phono stages were just something I did for myself! In fact, headphone amps were the first thing I started selling that I'd previously done professionally. I took a look at my old professional designs and figured out how to make them suitable for home use, and then I took a look at an old portable amp I'd designed for studio racks room engineers and turned the idea into the Voyager! For a long while now I've been trying to launch a little preamp - you may remember a thread discussing it on here some looong time ago. The problem has been being able to audition my design work on that. What I really needed was a good power amp and speakers to make it the best. Well, I reckon after making some modifications to some little Usher's (I can't get floor standers in here and many of you have the same problem too) I have some great speakers to audition with. But as for the power amp, the absolute best sounding one to date is a PA amp! Believe it or not, the 500 Watt Citronic pro500 that's curving the bottom shelf of my rack because of the sheer weight of its transformer iron, is the best I've ever heard, but it just lacks that extra spatial info I know exists. So I just thought I'd let you know I'm working on a power amp design - not a high powered one, but something around 30-35 watts - but it will sound big! And no, it's not a gain clone - this will be an all-discrete neat little design and it won't get productionized until it sound-stages like the phono stages do in the best systems. Keep following this thread and watch me develop it... Graham |

Very interesting Graham, looking forward to this!
Can you tell us which Ushers and what modifications you made to them? I ask because I am using a pair of stand mounted Ushers, which actually sound very good. Just wondered what changes you felt were necessary for the ones you are using. Still waiting for your invoice by the way Regards Les |
