"Old school" Gear overrated???

"150 watt" ZED Audio Crunch CR150 does over 300w @ 4ohm bridged with > .05% THD. (circa '92, USA built, CEA compliant)
"2,000 watt" MaxxSonics Crunch GPV2000.1 does 250w @ 4ohm with > .10% THD. (circa '09, overseas built, non-CEA compliant)

/thread

The Crunch is also not designed to make full power at 4ohms. Although your argument about which one it better made is correct, the numbers you're trying to show are irrelevant. The Crunch is also not rated to do 2kw, it's rated for 1kw.

Also, since when did CEA rate amps back in 1992? I thought 2006 was the first year for that stuff.

No they aren't. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

& the box of one says 150w amplifier....the other says 2,000w amplifier. it may not be rated 2,000w in the fine print, but that is what they are advertising it as to the mass public.

So the JL 1000/1 is better and more powerful than a Sundown SAZ-2500 because the JL does 1000 watts at 4ohms and the Sundown only does 600? Cool, good to know. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

And the GPV will do more power when gtiven the proper ohm load to do so. I'd bet it even does it's rated power, or very close to it. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

yeah, @ about .20% THD w/ a ridiculous amount of current draw.

Actually, I would take a 1000/1v2 over the SAZ-2500.

I would say better in the fact it does its rated power from 1.5-4ohm, But not better for more power no.

And besides you cannot really compair those 2 amps two totally different beasts.

Oh noes, .2% THD. And I'd bet it's more efficient than the a/b amp it's going up against. Nothing against the older amp, but it does not compare, power wise.

You know what point I'm trying to make, stop avoiding it.

Right, kinda like him comparing two amps and not using optimal conditions for each amp? That was the point of the 1000/1 vs 2500D comment, because I'm obviously not comparing the power output in a fair way for the 2500D. If I want 500-1kw at 4ohms I'm not going to waste my money on a typical class d sub amp that's designed to do most of it's power at 1ohm.

Ever heard of the saying "You can't compare "apples" to "oranges"" ...

I went through that phase myself where I refused to move forward in life and was reliving my past. All it did was cost me money and I found out that the old school gear was not capable of competing with modern day gear. I also found that my memory faded with time and some of those "best" amplifiers from my high school days still commanding a high price on eBay were easily outperformed by budget amplifiers of today.

Let's see what advantages there are to running old school gear:

1. They were hand made in the USA back when there were little quality control standards using through hole technology. Now those cold solder joints from the past will become BIG problems!

2. Electrolytic capacitors only last 10 to 15 years, so those will have dried out by now and are on the verge of needing to be changed. Heaven forbid a cap blows in the power supply section thus killing some transistors that have no modern day equivalent. Don't even get me started on the noise issues that pop up when the input filtering caps start to dry out.

3. They are inefficient class ab amplifiers that can be extreme current hogs. I had one old school amplifier that pulled 95 amps to produce 500 watts RMS with voltage in the high 13s. Conversely, most modern day Class D amplifiers would give me over 1,000 watts of power with that type of current draw on 13.8 volts.

4. Don't even get me started on the outright lies by manufacturers and marketing departments. They pushed unrealistic damping factors citing "cone control", claimed rated power at 11.8 volts, rated SNR at max power, and trained their sales associates to sell product based on other psychoacoustic factors.

Then again, this is a hobby. If you want to keep running the best possible gear from 15 years ago with a bank of batteries in your vehicle because they were the best when you were the captain of your high school football team, then more power to you. I'll take something more modern that has a better chance of working correctly out of the box than some old school product purchased off eBay that WILL need maintenance.
