The xtr just didn't do it for me. That power supply looks horribly weak (confirmed by the numbers it put up too) and I wouldn't put my $ towards that.

The 2500 ?

so making 3.2k under 1% THD for its size means its a weak power supply?

I'd like to assume you know how a well regulated power supply works. Ask yourself, why would an amp that makes so much power dynamically have a poor power supply? I'm not going to do all the work for you...if you read about the topology you'll know instantly why amps like this one, audiopipe, the Rockville, and every other cheap amp have such a large amount of headroom dynamically. Hint, it has nothing to do with the rail voltage ~hence poor efficiency as well.

They're actually pretty potent, they're just not over-built. Just in case we are talking about a different amp? Make sure to watch this in its entirety, pausing to view the results sheet with numbers all the way out to the right for the .8ohm load. -->



The 2500.1 makes impressive power in real-world burst situations that you would want for any good, dynamic music. Well over 6700 watts. Sustained abuse at 1ohm with anything less than the best electrical would probably not be a good idea, but that can be said for lots of equipment making the same power but is much larger and costs a lot more than this XTR.

The efficiency things always gives me a chuckle when you guys are talking about it. You only appreciate efficiency if you are operating well under the full potential of the amplifier's ability at all times. If you ever get anywhere near full output, then the amp is going to to what it does by pulling gobs of current. You can't get around this.

Nevermind my last post to you, I see that you already understand based on your last post. I think we can agree it comes down to proper application. This is not a good candidate for abuse, with or without good electrical. But would be a good choice for certain people who understand the limitations imposed by the build, size and cost.

Thing sounds great, though. Lots of control over the driver, good impact, nice tonal characteristics. And you can even defeat the subsonic filter. This is a big plus for my listening preferences.

you say poor efficiency yet i dont see that at all from actual real world use from people who actually own the xtr series. You can Just set the gain slightly lower (200 watts less) and viola no more 55% efficiency, you are well back up to the high 60s. cscstang with his 2200 on a stock alt barely any drop on his mustang.

As for your rockville audiopipe statement, none of those amps make certified 1 ohm power. This orion made 700 watts on top of rated. Not even close to the same league for any sort of comparison. Who even looks at dynamic numbers anyways, useless garbage number. Not to mention making more certified power at 2 ohm than most korean 3.5k amps clamped. To be honest, none of the korean 2k amps can hang with this amp at all.

you can talk topology all you want but results and test numbers are all there, no other korean 2k dyno'd even close to orion's certified numbers and they cost way more.

So it made the numbers they claim, that's great. My focus for you here is about how it makes power dynamically, I don't care (as you don't) about the numbers per se...but the reason behind why it makes those numbers. You're missing the bigger picture here. Theirs a reason those Korean amp's aren't making a ton of power dynamically or a ton over rated, the power supply is has much better regulation.

Yes, under normal circumstances with proper electrical I think it's a solid amp. I can agree that if the user knows what they are doing and doesn't abuse it, it will be fine. But for the vast majority of people (myself included) I like having the added comfort of knowing my amp is overbuilt and will last me.

Now you guys have me wanting to pick one of these up to compare side by side with my other amps though.

And Jeff has a point in it making certified power and the efficiency just by backing off a hair more from clipping. I didn't pay enough attention to the video I suppose.

This is such a classic argument, too. I remember back in the old school days when some guys didn't want to use Soundstream Reference due the unregulated power supplies. But wow did those sound great on music and look at the "garbage" dynamic numbers they make. Not so impressive numbers for the sustained power output, actually a little below. The old Orion stuff was the same way, lower than expected for RMS but real nice dynamic burst numbers.

Again, this comes down to application. On this SPL forum, not many will be interested in dynamic performance but that has a direct impact on music. Tones, not so much. You need the tightly regulated power supplies for that. Of course, the bigger picture is how reliable any of these amps will be in their respective applications. Pick the type you need and feed it the proper voltage/current for the long haul. Beyond that, it comes down to responsible usage. Even an Audiopipe should last if all of this is taken into consideration. Okay...maybe not. But you see whumsayin'.

I could send you mine for testing if you promise to be good to it. If you blow it, you just have to help me buy the 4000.1, lol.

My thing is if i cant wire to 0.5 or lower and subject it to 11v from time to time, it isnt useful in my application. I like to abuse **** and not worry.

I ran my dd m3 at 0.5 on stock alt for 4 years railing on it daily. Thing lived around 12v

That's pretty impressive. There's no denying that overbuilt is the way to go for bulletproof, peace-of-mind, reliability.
I don't think you could get away with starving this amplifier on the regular.

thats straight up the taramps bass 12k lol... can go down to 7 volts and wire to .25 ohms ON music.

Op. You find one? I'm courious about the new tramps. I might sell my nc 3600.1 if the price is right.

 

[ABSOLUTEAUDIO 10+ year member]

how about a new taramp DSP3000? 3,000rms1ohm 12.6v and 3,592rms1ohm 13.8v.

Haven't found jack lol hm u asking for that

i have a NC3600.1 im thinking about selling. does 3600@ 14.4 @ 1ohm and 4200 @ 14,4 at .5

i need something abit stronger at 2ohm.
