    Any thoughts on Samson power amps? I am about to purchase 2 (the S1000 and the S700). I like them for the weight, less rack space, and they sound very good with the limited trials I have done with them. The sales rep has put it in writing that i can reurnt them in 10 days if I dont like them. I would like some itelligent opinions. I will be running them into 2 Eden 410 cabs and 2 Peavey 118 cabs with a tube preamp, crossover, and a stereo 15 band EQ.

    If you could time your purchase so you can gig with the rig within the 10day period it will help. Ten days aint a lot.

    Your right and that is exactly what i am doing. I just wanted some other opinions/experiences on any quirks or reliability issues. Thanks for your reply jc.

    Thats why i am asking for opinions, i have never used them.
     
  5. Due to recent decreases in price from QSC, Lord Valve AKA "Fat Willy" has some EXCELLENT deals going right now on QSC PLX and RMX series amps. I'd far rather use any of these than anything Samson makes.

    Here are the prices he emailed me:

    MODEL # 8 OHMS 4 OHMS 2 OHMS BRIDGE LIST YOUR COST
    (DELIVERED!)

    PLX-1202 200 325 600 1200 $858 $509

    PLX-1602 300 500 800 1600 $1198 $599

    PLX-2402 425 700 1200 2400 $1498 $799

    PLX-3002 550 900 1500 3000 $1798 $899

    PLX-3402 700 1100 1700 3400 $2098 $1099

    MODEL # 8 OHMS 4 OHMS 2 OHMS BRIDGE LIST YOUR COST
    (PLUS SHIPPING)

    RMX-1450 280 450 700 1400 $649 $429

    RMX-2450 500 750 1200 2400 $899 $579


    (sorry for the formatting, it really needs a monospaced font to make it easy to read)

    I'm not affilliated in any way with Willy, other than as a very satisfied customer. I bought my PLX-2402 from him before the prices went down, and even then he had the best prices of anyone I could find. Here is the contact info for him:

    "Lord Valve" LORD_VALVE@prodigy.net

    Michael,

    Those are great prices. Every place I've checked sells the 2402 for $1050. There's not much info on Lord Valve's web site. He's really legit, huh?

  7. Yeah, very legit. He's a fixture on rec.audio.pro and has been for many years. He's obviously not a website designer though. ;-)

    I've bought tubes and my PLX-2402 from him, and I've recommended him to a bunch of folks who have bought QSC amps from him, and all have been impressed with his service.

    He's a very straight-up guy, you won't have any problems with him.

    IMHO poweramps (at least the solid state ones) should have no specific "sound" at all. They just make it louder.

    I was told by a sound engineer whose experience I really appreciate that "If two power amps sound significantly different, at least one of them is broken."

    When it comes to poweramps, don't compare sounds. Check guarantee, reliability, impedance (Can I go to 2 ohms?), size, weight, but not sound.

    Worst sound you can have is no sound at all because your power amp is overheated, broken, beyond it's limitations.

    Although I usually think of power amps as not having a sound of their own, I don't agree that they cannot have slight sonic differences, even when operating normally. There can be significant differences in damping factors between amps, which may cause one to render sounds muddier than others; how much they distort (THD, IM) can also become audible; and there are perhaps other things, such as slew rate, that can make for slight audible differences. So it can be legitimate that someone claims one amp sounds better (for his/her application) than another.

    Another thing is (for solid state amps, anyway), things can get a little out of whack (transistor bias, for example), and that can affect the sound, too.

    Lately, I've started to consider total power draw as another possible factor. If you have a big, inefficient power amp that draws a lot of amperage from the power line, the line voltage may sag more than it would with a similar amp whose efficiency is higher. The voltage sag might contribute to audible differences (such as early clipping) as well.

  10. While I agree that power amps should not color the sound, the fact is, many do.

    I have found, for instance, that the Mackie 1400i I had has a very soft, soggy-sounding bottom end compared to the QSC PLX-2402 I use now. The QSC is MUCH more solid and punchy sounding.

    And for old guys like me, weight is a significant issue in power amps. All of the QSC PLX series amps weigh 21#, which is pretty significantly lighter than most conventional amps that don't use switching technology. If I was 18, I might not care, but I'm not, so I do. ;-)

    Has anybody used any Stewart products?

    I'm using a Stewart PA-1000 and really like it. I've used Carver power amps in the past and they sound good but this Stewart sounds even better. It has more power and the increased headroom really lets the bass sound "breathe".
    It also runs very cool so it must be efficient.
