Jule Amp M700

It looks bigger than I thought it was; which is fine.
It's still not big.
From your descriptions, I presume I'd like the 700 better; and I think a clean, more open power amp is probably a great fit for the tube preamp; letting it's characteristics pass right on thru.

Cool stuff. Exciting.
This, and the wrecking ball deal. Cool cool cool.

The "bigger" thing is kind of interesting.

Much has to do with cooling. I learned (from some great customers in very hot climates. "Thank you Sammy.") that a lot of cooling is a very good idea.

The size also has to do with what can be accomplished in a metal shop. The giant machines that build the faceplates have limitations as to how tight a bend they can make. When these were first designed, I stood in the metal fab shop beside the owner as he worked toward what I wanted. This is as tight as the curves could be built. Hence the top to bottom dimension.

In speaking with as many great speaker builders as I could, none of them made a cabinet smaller than the outer dimensions of the M700.

And it makes for a very stable base for whatever we wish to set on top of the M700.

My first impressions follow along the same lines. The sound seems more "open" or "flatter" in both directions. "Faster" is also a great way to describe her. Kinda reminds me of a Stewart amp with how fast and defined it is, especially down low. I thought the notes were jumping outta my fingers when I was playing the Minnie, but after an A/B test there is a hugely noticeable difference. Nuances are being more clearly reproduced through the M700. The Minnie defiantly seems to be rolling off both lows and highs, making it seem a little darker. I have also noticed a large difference in the way my pedals sound. I recently picked up a new Nimbus with the new bass and high control. With the Minnie I felt like the difference was nominal when I tweeked the high setting. The M700 makes the control super usable now. I was able to get some really "shimmery" tones.

I was not crazy about the form factor, or the front input. After 2 hours with it I could not care less. It could smell and look like a turd on my amp as long as it sounds like it does.

Lastly.....Noise. I did a dry test A/Bing the two amps. Basically o just plugged everything in and turned everything all the way up. No signal, just the bass plugged in like in between songs. The Minnie was noticeably noisier. I know that the fans are simular or the same but I feel like the Minnie's fan is also noticeably louder. All in all I feel like the M700 is just way less noisy. The M700 also seems more powerful. Maybe that is just the flat response making it feel so much bigger, but I feel like this thing is going to melt my face off.

I did notice that with Monique all the way up I was not able to get the M700 to even flash the yellow indicator on the front. I was playing a passive Smith so I will have to try the active Dingwall later.....

Different fan and fan philosophy entirely.

The Minnie does an awesome job of removing the heat from the Amplifier when we consider the small form factor. Amplifiers in this power range generate heat similar to a 70 watt incandescent bulb. All that heat must be removed or the amp gets "unpleasant." The larger size and all aluminum chassis of the M700 cools enough by itself that a much less aggressive/noisy fan is required.

Yes, but it is quiet and from what Jule says, probably overkill. One reason for the larger enclosure is to provide a huge heat sink. I haven't even noticed it getting warm yet.

If you touch near the middle of the bottom, you will notice it getting warm. The entire textured bottom rapidly dissipates heat. The 5/8" tall feet keep enough air flowing beneath to do plenty of cooling.

Pound rescue - half Russian Blue. He's awesome.

I think Minnie is rolled off a bit on both ends. From what I can tell the M700 is flat in both directions. I'll gig it tomorrow night in a loud situation but from the gigs already along with at home I don't think it will break a sweat. One advantage to using a module at below its spec.

Kinda fun to put in a bit of over-kill. The power supply in the M700 is rated at 1200 watts continuous. No dips. Nowhere. I think this goes back to racing open class motorcycles in the desert. There are times when more power is a very good thing.

are the feet important for heat dissipation on the Monique? I removed the feet a while back and like it without them. I have the Monique sitting on a power supply that does not get hot.

So after a few days I can say i am very pleased and surprised with the M700. I wasn't sure how much of a difference I would see side by side on my gear. The results have change my mind about just how much a non tube power amp can effect tone. The looks have really grown on me, to the point where I think I like it more than the Minnie. Minnie fit for sure, but I agree that with the larger base it looks a little tougher and more stable. The power, clarity, and quietness of the M700 are like nothing I have ever heard. At real intense volume you cannot even tell the amp is on until you strike a note, when you do it feels bottomless and is soooo fast and articulate. The low end I am getting from my active Super J is on a different level. The EQ on Minnie feels more powerful, slight adjustments are more audible. And heat? Grant it that now is not the hottest time of year in Texas but this thing seriously does not get hot. I mean not even slightly as compared to any other amp I have ever had. I will need to work out a case or something to make it easier to carry, that studio slips bag sure was nice with the Minnie.

All in all I am Super happy!! Thanks Jule!!

The Minnie and the studio slips bag will likely be posted in the classifieds soon.

For some reason quotes are not working with the iPhone, so....

Anyhow, to answer Baird above, I'm quite aware how to wire the equipment..LOL.! :)

Seriously though, if you check the new web page for the M700 on the website, Jule states that the input sensitivity on the M700 is as low as -26db so you can theoretically plug your bass directly into the M700 as well. Of course it won't be as loud as coming from a preamp into the M700, but you can plug a bass directly into it.

Fwiw, you can also do the same with the Minnie. I have done this once out of curiosity at home before and it works just fine (active bass, didn't try a passive bass). Sure the output is low, but it works.

Baird, check out the M700 webpage and you'll see what I'm referring to. :)

My bad. Been some mention lately regarding why the M700 input was on the front and not the back where many are used to seeing it on poweramps.

In the Monique thread Jule has talked about this before- someone was asking about multiple inputs, or an additional read input on the rack unit Monique.
(Note it isn't a direct answer to why the M700 has a front input instead of a rear input, but I think we can glean from it that Jule ultimately has gone through these thoughts, and has our best in mind with the choices he makes like this.)

His reply was:
"We would have to break both sides (and preferably the third earth ground) to create a situation where we were not able to change or radiate in or out of the signal chain at the pre-amp input point. Doable, certainly, but a bit messy. I would also expect a difference in tone and characteristics between the rear and front inputs - Nasty. [not bold or emphasized in original]

Simplicity in this area (physically) is greatly of value. Added to the issue, and not mentioned earlier, is the very high gain of the first input stage, and with that the nasty susceptibility to both receive and/or emit radiation in or close to the audio spectrum, and that seriously detracts from the performance.

The length-of-cable issue is truly Yes and No. The Yes part is that anything that electrons move through and a dielectric is involved does add capacitance with increased area/length. That is the "YES" part you can read in a paper specification. The No part is that some of these instrument cable folk have fiddled/invented ways of balancing that Length:Capacitance issue so that their instrument cables do not follow the paperwork mathematics of what you and I would expect. Their instrument cables (often quite pricey) do not directly add capacitance with length as one would think from the paper specification, or they do so in a positive manner. They are messing with Physics in ways I do not pretend to grok."

So what are you using to carry your m700? I know the gator 1515 mixer bag was stated here, but what others? I would like a better fit than the gator bag.

I found this that seems like a better fit, a bit smaller exterior than the gator, but a little more money.

Any others? Thanks.

Susan at Studio Slips will have a bag ready soon. In the interim, I have found an off-the-shelf flight box that is working for a couple of customers. Not the fancy-est, but it does the job. Invalid Link Removed As time goes on, I will ask Carlos at Anvil Cases to make up a more customized box for the M700.
