I have done extensive dummy load testing of many many amps while looking for specs and standards for our new OEM line.

I can say this with certainty but don't have time to write out all the numbers.

The Nyla while drawing only a maximum of 21amps from a solid 120v service will outperform a Crown 3600vz and QSC PL340 on output of voltage into a dummy load on various sine waves at 30Hz, 50Hz, 85Hz, 1KHz, 15KHz and heavy modern dance music.

The crown 3600Vz will slightly outperform at 50Hz and 85Hz 6v , but will draw up to 31-44amps from the service and be in hard limit.

The PL340 will slightly outperform at 30Hz and 50Hz by 2v per channel but will draw up to 31amps to do so in hard limit.

The Nyla is conservatively rated 1100 w at 2 ohm.and 800w at 4Ohm

All tests were done at 4 Ohm. in stereo both channels driven.

And the Maya, which is very conservatively rated at 1500W x2 @ 2 Ohm (5Hz to over 20kHz) in my experience will walk all over a MA3600, especially in the low end range. The kick is so solid and snappy I could never go to any other amp for low end alone. Then there's the new Luna which will easily do 1500W x2 @ 4 ohm, i'll leave it at that, it's a beast.

All my Thrive amps run comfortably on 120V/30A circuits and have never tripped a breaker in the well over 2 years of use.

It appears the current drawn reflects the amplifier's true wattage. I've learned to appreciate ohms law more and more each day

I run all my thrives on 20A circuits and never tripped a breaker in the past 4 years. On headline dj nights, we are running them at 95% of its capacity. They are great amps, never go down once. Funny thing was my Crown 3600vz went out on us!

is there any test lately on Crown IT Series? or its just for similar watt amplifiers? I work with It-8000 at 4 Ohms, never give any problem,. and likes how its sounds, however will love to hear comments about the performance of them.

Hi.

The I Tech 8000 was benched but never faired well. However, the amplifier ratings are based on "burst" and the test were sine waves.

If you like how the I Tech performs does it really matter what someone else feels about them?

I dont think

there is any reason for this to get personal, Adam loves the product and expresses how he likes the product line, Just like how many of our clients like the product line globally using them in a wide range of applications, from pro apps in clubs under very heavy use without failure with incredible clarity, to Recording studios for monitor systems for mix downs, & we have clients that use these amps on their home Audiophile systems that love the way they sound and have compared them to very well respected audiophile amplifiers, then made the switch to Thrive because they heard the amps and liked the way they sounded better on there speakers then the brand X they had previously powering there speakers.

Adam has used our amps and compared them to other products on a site he did a system for in a real world situation installed 3 yrs ago, and the product has never failed. He also compared the Thrive amps in a AB test against what is considered today as very high quality amplification & technology @ a major speaker manufacturers facility on there speakers, and expresses how he likes the Thrive line over other brand he compared them to at this facility, this comparison AB testing was done with the engineers that designed the speaker line in there listening room under critical listening conditions where they test all there speakers, and the engineers were astounded by the comparison. Soon after this demo the VP of the manufacturer called me to tell me his thoughts on the amp, as he was blown away and said all this time we thought this other amp was very high quality and the Thrive exposed its flaws.

Just as Nathan has expressed his thoughts and opinions on our amps to other products, there is no sales pitch there, it is just there take on what they like & heard and prefer to use over brand x, just as you expressed what you have liked in the past from 1 product to another that I have read and valued your opinion, is that a sales pitch No, but is it your opinion on what you like & need ? Yes.

Jus my 2 cents

It is unfortunate that it has turn into this.

Let me state for the record that this has nothing to do with the Thrive amplifier, which is why I stated, and I quote:

The Thrive Amplifier could possibly be a great amplifier. However it does not meet my requirements.

In addition to:

The problem arrives from not reading what I stated properly, quoting what I stated and pursue marketing an amplifier, taking pot shots on the Crown I Tech 8000 and paying no mind that the Thrive amplifier does not meet my requirements from a wattage perspective.

Why atf104 would take it upon himself to quote me after I stated the amplifier is not powerful enough for my requirements with more praises on how it is “built like a tank” only he can answer. I can assure you if this was a means of helping a fellow sound man it was not and, those who are familiar with me knows 99% of my post on audio message boards are based on answering technical questions.

It appears a few a becoming at tad upset based on me not finding the Thrive amplifier suitable for my requirements without paying attention to what I stated in regards to the minimum output wattage needed for my requirements.

That is my bottom line, which the Thrive amplifier cannot provide.

Again for those who are content with what the Thrive Amplifier offers in terms of output power, congratulations. As for myself it is not enough power, which anyone can “do the math” using the ohms law calculator that Vman has graciously offered to see how much a difference there is between a 2200 watt amplifier to a 10,000 watt (my minimum requirements) amplifier from an output voltage perspective.

http://www.the12volt.com/ohm/page2.asp


There also seems to be some false assumptions on the Crown I tech 8000 (although I am not looking to purchase that amplifier) in terms of power consumption. Could someone show me where Crown states the I-tech 8000 can/will offer 8000 watts drawing only 20 amperes on a 120-volt line source?




http://www.crownaudio.com/pdf/amps/137435.pdf


I really don’t have time for overly emotional individuals when they assume not pursuing an amplifier they recommended offensive, when they do not take the time to read exactly what the person is looking for. Such behaviour is too childish for this 30-year old.

Any adult can clearly understand that the recommended amplifier will not be up to the task (based on Nathan’s wattage bench test report) from a dB standpoint based on the required watts needed to offer +3 dB (minimum) headroom in terms or output from the Crown 5000vz.

Best Regards,

Thanks for mentioning this Adam and why you see our amps conservatively rated from 12 hz to 50K..

We never believed in the 20 to 20 ratings, we believe in designing and spec our products with a very wide, dynamic hifi sounding product that sounds good in any portion of a sound system, not just known to be good on subs, or high freq, it has to sound good in any band desired, subs, midbass, low mids mid highs or tweeters.

We use our products in hifi audiophile systems, studios ( a very famous nightime talk show on tv uses Thrive Amps on the monitors to mix the show) & obviously in night clubs

Hey Nathan, you should send a Luna over to David Lee. He'll give it a good run-through and document DB measurements. It'll bridge into 4 Ohms or would that call for a Maya?

If he says it out-performs other amps, we just might have a new contender!

I use Thrive amps for the past 4.5 years.
It has been very reliable, in fact, 3 of the brand new Crown 3600 vz went down within the first year.

I had the power switch replaced 2 times on one of the Thrive amps, and I got the parts free of charge within a week!

I like Thrive product and its perfect for my use.

But I can also understand what other people were saying about there is no specs on these amps.

There’s enough basic specs to get somebody started. The biggest one has a 20 amp power inlet so we can extrapolate they draw 20 amps or less at their rated output and it has a 20 amp pop circuit breaker. Are these UL or CE accepted? If not, it’s not wise to use them in an installation as in the off chance they cause a fire, no insurance company will cover any losses.

I would wonder if they are power limited below a certain frequency to not exceed the 20 amp mains (as they are rated down to 12 Hz).

I’d like to see how they perform into some big power hungry subs compared to say a PL380, or an offering from Lab.gruppen or Studio-R.

Paul,

I am more than certain that 12 - 50 kHz is the frequency bandwidth. All amplifiers offer such ratings. They are located in the manuals. Manufactures promote 20 - 20,000 kHz in terms of frequency response. However, no professional amplifier is limited to 20 - 20,000 kHz unless the amplifier is all digital and limited based on the Nyquist rule. Why am I telling you this, which you know already?



Nevertheless,

The internal arrangement resembles my old Crests Professionals.

Who ever owns this company I would suggest you take down the internal photos of the amplifier or at least make them smaller. If I can find out the voltage rails by looking at various parts of the amplifier, I am quite sure someone who designs amplifiers can see much more.

Best Regards,

Elliot,

You’d know more about the individual parts and their ratings than most people including myself. I agree, they are similar in construction to Crest amps. Not necessarily a bad thing. It’s very simple inside, what kind of protection does it have?

There appears to be many items that aren’t well secured. This amp may not survive long on the road. It certainly wouldn’t survive the Crown or QSC drop test.

I’d still want an experienced ear to beat them up next to other amps. Remember Elliot, the first & last lesson in SMAART is if everything says it’s good but your ears say otherwise, it’s not good.

Hopefully the manufacture will create a PDF Manual for, showing the internals of an amplifier just brings forth more questions.

To my eyes, the faceplate always resembled a Crest Professional Series, with an LED array from the old BGW 750C. I cannot say I was surprised with the arrangement inside. It basically confirmed my assumptions.

I actually use my ears more often than viewing SMAART graphs and, use such illustrations to confirm my findings.

I am shocked Scott passed away. My thought patterns have shifted upon hearing the news.

Best Regards,

The layout of the amp might be similar, but only in the fact that having a tunnel for cooling, and keeping dirt out of the amplifier , is just a good common sense design.

The Transistors,their mounting, topology, pcb, rf filtering,limiting, output protiction, preamp stage,preamp power filtering, and ridiculously overbuilt power reservoirs and where they feed into the poweramp circuit, are all quite original.

Its like watching people fight over the folding of horns. Well, it is 2010 and there are only so many ways to fold a horn, port a box, and lay out an amplifier intelligently. I would take these in a flat black project box any day. The look is not for everyone, the road worthiness is not there nor was it designed to be road beaten. But they do sound like a dream, and when the money allows, are always going to be my first choice.

I had them in Level, here in Chicago for years (4 I think?) 6 days a week, about 6 hrs a night, full out House , Rap, and you name it. They never ever had a flaw. Crest CA 9 and 12's dropped like flies, Thrive never did.

Like any item, not for everyone, but for those whom have heard it, it beats the pants off of many many items.

You may be over analysing things for I don't see were the fighting came about.

It is merely talking shop. Once a manufacture takes it upon him or her self to offer the internal parts of their product for all to see, you will embark some that will comment on the components, or in this case the arrangement of the design.

It regards to Crest, it shares a lot of characteristics of the old Professional series in terms of how the components are arranged. Although no longer in production, Crest Professional Series is still classed as a highly respected design.

I don’t know any small manufacture would consider that degrading when there are lots of small companies mimicking amplifier arrangements from designs that are inferior to the Crest Professional Series.

Hey hey, no fight here from me. I was just pointing out it is not some Crest Clone.
