It's hard to say without more info.

If you're looking for high performance--i.e., extremely high accuracy, ultra-low noise and distortion--at a decent price I would recommend a look at the PLX series (including the old PLX series if you're shopping used gear).

Being accurate, the amp will sound only as good as what you put into it and what you listen through. It won't make bad program material or bad loudspeakers sound good.

Fullrange or subwoofers?, posted on September 22, 2008 at 00:33:26

If it's for subwoofers, you don't need anything fancy. Consider the lowly Peavey PV8.5C, and the CS800; both do over 400 watts/channel into 4 ohms. I've used the PV8.5C as a sub amp, and the fan is pretty quiet in low-speed mode. It only kicks up into high speed in very hot weather, or when the music is really bumping. Taller amp cases allow using larger diameter fans which move more air at lower RPMs, and therefore are quieter than 2U (3.5" high) amps. The only problem I've had with the PV was when the very dirty fan didn't start up and it overheated and (rightly) shut down, and once running into 2.66 ohms with faulty generator power. No permanent damage once it cooled down.

Are you wanting something small and lightweight or good sounding? You can't make a blanket question like that without specifics. BTW, QSC makes some real crap on the low to mid level. HUGE failure rates in some models. So compare apples to apples.

Used it in the PA rack for several years, and now am using it in my home audio rig. Despite what you may have heard, it sounds great, and I've never had a bit of trouble with it.

It's very quiet, with a neutral, 3-dimensional sound quality. Very nice.

I would also say it matches your criteria of good bass, power, headroom and reliability. The 1400 is 200 watts RMS per channel into 8 ohms and 300 watts per channel RMS into 4 ohms, both channels driven in stereo. you can also bridge it for I believe, 600 watts into 4 ohms, but I'd think a couple of hundred watts per channel should be enough for about any normal home audio application.

Cheers,
Bobbo :-)

These old amps with obsolete parts will be hard to compare, unless they have been properly refurbished. And then how would you compare them if they have been refurnished with new parts? They would not be the same. So me telling you what they were like new, when I was selling these things, is not going to mean jack.

Back then QSC amps were not known for reliability, and they were expensive. We sold exponentially more Crown than anything else. QSC was ok for low wattage, high impedence applications, in installations with low impact content. That was our experience.

These two amps were just ok back in the 80s. They were not industry standards for professionals. Neither would make it on a tech rider.

There were different versions of the 1400 made. You can check out their support forum, which is very good, for details. Those 7300s were real EV prior to OEM'ing. EV has since purshased Dynacord. They make EV amps and processing now.

Back to the question, I would not seek out either of these amps to use in my home audio system.

Qsc's Tech support is TOP NOTCH! no other pro sound company has as good of a tech support team. NONE! The QSC forum is answered daily, and for a repair tech like myself, I can email or post in depth tech questions and they give you real answers back. Not just call an authorized service center.

The EV amps are generally dynacords by design. not much info is available about them as far as i know. they are more popular in Europe then in the US.

The QSC 1400 isn't a lot of power if i remember correctly even bridged. But they will run 2 ohms as long as they are clean inside, have a plenty of AC power and have adequate air flow.

I think the EV 7300 is more power.
