    Mad power and an equal amount of sound quality. There was a small amount of buzz about this amp on some Home Audio boards. Some people said such an inexpensive amp just couldn't sound good and had no place in a Home Audio rig. Funny thing is, this was said by people who hadn't heard it. Those who heard it in their systems were amazed at what they heard. Even more impressive is that it delivers sonic performace rivaling that of MUCH more expensive audiophile amps. I'm driving a pair of Magnepans which are VERY revealing speakers and they reveal this amp to be wonderfully powerful and transparent.

    The bass is clean, tight and powerfull. The mids are totally transparent. The highs are very detailed, clear and extended. Whatever your source supplies, it will be faithfully passed on to your speakers. I've been an audio enthusiast for over thirty-five years and these ears know good sound when they hear it. Detail, dynamics and headroom. This amp has these by the boat load. Listen for any sonic warts or shortcommings and you won't hear any. Often, high end speakers present difficult loads, have low sensitivity or just plain don't sound good unless driven by a powerfull amp with plenty of headroom. Usually these amps are very expensive. With a EP1500, you can drive these speakers without going broke to do so. If you're going to seperates for a music system or bypassing your HT receiver's onboard amps to get big power, this is your ticket. A big, high quality SS amp just makes speakers play better!

    They’ll sound better on the H&K, but not because of the power rating. The H&K is a better amp, designed for sound quality, whereas the pro amp is designed to be able to take lots of abuse, such as running at 100% power for extended periods of time.
    Take this advice from a guy who bought a pro amp, and is now stuck with it. :)

    The higher number of watts is less a factor than the quality of watts, and amps (current) even more so. Most PA amps sacrifice sound quality for ability to provide volume in larger rooms (venues as apposed to home listening).

    These speakers will clip and blow tweets when I put up vol to high so I thought more power will solve this

    Well, that's another question altogether. The answer is likely "yes" that this might solve clipping issues. Will it play LOUDER? Most likely. Will it sound BETTER? Very unlikely.

    Loud. Good sound. Inexpensive. Pick 2 of the 3.

    First lesson, all watts are not created equal.

    Second lesson, to increase the volume level by 3dB it takes twice the power. Going from your 120wpc amp to a 300wpc amp will gain you roughly 3.5dB.

    Third lesson, one can make just about any amp clip by turning up the volume too far.

    Fourth lesson, a cheap amp gets you bad sound.

    Fifth lesson, a good amp costs money.

    6th lesson....if you like it louder, you bought the wrong speakers. Buy speakers that can handle that loudness like PA speakers, Crappier sound, but they'll go louder.

    7th lesson....everything has it's limits. Turn the volume knob down if you don't want to keep blowing tweets.

    8th lesson....those "recommended watts" on the back of speakers mean little.

    9th lesson....get your read on and learn about audio. More to it than just buying a pair of speakers and cranking on the volume knob.

    If you want loud, get Cerwin Vega. About all they are good for is going very loud.

    Now if you want sound quality please listen to these people.

    He plays a good game of golf though, have to give credit where it's due ;)

    Seriously though, stick around, it's not that bad here and you can get some really solid
    advice. NO ONE will intentionally steer you wrong.
    So, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

    Rotel makes very good amps. All things being equal at the very least it will be equal to the HK since the only job that the Rotel has to do is power your speakers. Go for it.

    My Teen setup was 15" Cerwin Vega (D9 I think) and Polk bookshelf speakers. When I wanted it loud I used the Vegas, when I wanted SQ I used the Polks.

    Car audio to home audio is a a lot different. Cars are small compared to homes. A lot more space to fill in a home.

    A receiver has a lot to task the power supply with. As in car audio you get better cleaner power from a separate amp.
