    I want to rack up my SWR Grand Prix with a power amp to run into an Ampeg 410HE - 500w, 8ohm. Throw me some suggestions guys.

    I use a Peavey IPR 1600. Good amount of power (for what I do anyway), simple feature set, well built, lightweight, great price. Crest ProLite is also a good choice IMO.

    I like the IPR's too. Light, powerful and inexpensive.

    Do check to make sure whatever amp you do pick has an input sensitivity that matches what your preamp can provide. This is probably the biggest concern you should be having in regards to picking a power amp. An amp like the Peavey has an input sensitivity of .775v, while some other popular and reasonably priced amps range from that up to 1.4v.

    Can the IPR1600's be bridged?

    Yes. You need to build a special cable.

    Yep. I do this regularly. If you're bridging into an 8ohm load with the 1600 you'd be looking at ~1030w.

    ;)

    Yes.


    I didn't mention that I use the bigger IPR3000, and I bridge into a 4ohm load for 3000w.

    Of course, if you run just one side, you're getting 290w...which is probably reasonable.

    The Crest prolite has built-in bridging - no special cable needed

    OP, look at sensitivity specs, when using the SWR.

    Both the Peavey IPR2 and Crest ProLite2 use 0.775v sensitivity specs.
    These amps are much easier to drive to full power than my PLX 3002, etc.

    Had a crest Ca6 that was incredible, now running a Peavey IPR 1600 love both don't miss that weight.

    First off my bona fides; I have used extensively and / or toured with the following:

    - Crest CA9
    - Crest LT1000 and LT2000
    - Crown Power Base
    - Crown XTI1002 and XTI2002
    - Peavey IPR3000 (first version when the first came out)
    - QSC GX7
    - Carvin DCM1000 and DCM2000
    - Carvin HD1000
    - Carvin DCML1000 and DCML2000

    Out of all of these, the CARVIN's are the standouts in terms of outstanding value and performance. I toured the DCML1000 for probably 100+ shows in a row and it never flinched even once. The DCML2000 and Crown XTi2002 are tied for my favorite "lite" power amps, with that decision being based on how well they "thumped" in the low end.

    The worst performing out all of these were the Peavey IPRs. Compared literally A/B with the DCML (rated at less than half the wattage) and having roughly equal input impedance the DCML just absolutely TROUNCED the IPR. People who's opinions I trust have dismissed the IPR series output as downright fraudulent.... HOWEVER, since the IPR series has some VERY outspoken fans with anything from zero to extensive basis for comparison... I will say all of this was years ago when the series first came out.

    Bottome line.... CARVIN.... IME, IMHO, FWIW, YMMV etc etc

    Many people are using IPRs quite happily and without difficulty.

    I am currently using a QSC2402, but I just bought a Micro Thumpinator so that I can have an HPF in my signal chain no matter what power amp I use. I am hoping with the thumpinator I'll be able to pull off using my Carvin HD1500. I had themrmal shutdowns with the HD1500 previously but my cab's crossover had a faulty cap in it... now fixed.

    Failing that, I will likely get a Crest Prolite 2.0. I had the IPR 1600 and was not terribly impressed with the build quality. It never failed me and sounded decent in the short time I had it... but I never pushed it. From what I read the Prolite series by Crest is the next step up from the IPR stuff.

    If you don't mind the 47+ lbs, a Crest CA6 or CA9 will slam you against the wall. Major thud for cheap when purchased used. Many lead sleds are getting dumped for lighter gear and can be scooped up cheap.

    The important point here is for the OP to check the input sensitivity against the preamp he's working with. That may rule in or out a bunch of brands and models.

    I don't know how much more I can do to further frame my opinion as an OPINION in order to avoid negative personal responses like this. Eh well. :D

    I play a sans amp RBI with a swr 750x as a power amp
    (Just plug a pre into the effects return)and i actually use a 410he. The 750x power section sounds great using the RBI as a pre. The setup still allows you to control master volume and the limiter controls on the 750x

    My suggestion is to buy a used bass head that can be used as a power amp. Doesn't have to be anything flashy, an ampeg b4r has plenty of power @ 8 ohms. Would match the cab and has a power amp in jack you can plug your pre into. Pa power amps can work but i just like using a head, if for any reason my pre amp doesn't work i can still play the head by itself and get through the gig. I've been debating getting a svt7 to use as a power amp but I've hesitated after reading a lot of horror stories. I mainly am considering the svt7 because of the dramatic weight difference and it matches my ampeg cabs.
