Sebna, check out this link:
http://www.tweakaudio.com/EVS-2/Job_225_mods.html
This is Ric Shultz's website called TweekAudio. He's been modifying stuff for a very long time. He loves the Job 225 and lists some mods he can do to it. Don't know if any of the mods listed will achieve what you're after but it's worth a shot to contact him and ask.
Hope this helps. |
Thanks Devilboy for coming back on this.
I have same approach as you. Would prefer not to add anything to the path if not an absolute must, hence the idea of moding the internal circuit.
I am afraid that all the volume regulation with this sensitivity and output of mu Pre is going to close in 1h span (so lets say min listening levels at 8 o clock and blowing up the speakers at 9 oclock).
I guess I will have to try and see for myself.
Pre is in analogue domain and it is Eximus DP-1.
Cheers |
Sebna, a faster way might be to add some Rothwell adapters to the rca inputs of the job. At least that way you wouldn't have to open it up. Obviosly now you're adding something else to the signal path. I wouldn't do it, just throwing it out there. It does seem that 9 o'clock would be loud and 9:30 too loud. |
Hi Guys,
Good read those 4 pages.
Have anybody tried already to lower the gain of this amp by changing the resistors? I would be very interested in this mod as my speakers are 95db/w and my Pre pumps 3.7v so I am afraid I will be adjusting the knob using microscope... (no remote).
Thanks |
I was shopping for an integrated when I reluctantly bought the 225. I say reluctantly because I knew that meant going past my price range, not in amplification but in the additional preamp and interconnects I was now committing to. I'm excited about any product Goldmund/Job releases. |
latest I heard was that preamp possibly by June and monoblocs by year end.
I would love to see an integrated with simple remote. |
I use that combination and it sounds great! |
I wonder how the Job 225 would sound with the Wyred4Sound STP pre? They are the same price-category. $1700 and $1800. |
Hey, I just wanted to tell everyone that Ric Shultz from tweek audio dot com loves the Job 225 (calls it a giant killer), and he lists mods he provides to it. As I wright this, price has not been set.

Robertsong,
Specs on 2CE Sigs is as follows:
IMPEDANCE:
7 ohms nominal 4 ohms minimum.
SENSITIVITY:
86dB with 2.83 volts of pink noise input at 1 meter on axis.
RECOMMENDED AMPLIFICATION:
40 to 160 watts per channel into 8 ohms.
The Treo is similar. So my opinion is as long as you don't play concert level you will be fine. They are an easy impedance load so I would not worry. I bet you will be amazed at how good the Job 225 sounds.
Devilboy,
Yes. I should know the details is a few days and receive in a couple of months. Stay tuned. |
Joe, Norman tells me both of you have your eyes on a passive for the Job. Keep us updated. |
Anybody think the 225 would work with Vandersteen 2CE Sig II's or Treo's? I just read the 6moons review and I can't help wondering. |
It's only an issue if the preamp passes any DC. According to Srajan's review, some tube preamps could. If you put a passive preamp on the Job you might be better off. |
GRK, what are you using for a pre-amp? Can anybody speak to the DC coupling issue that seems like it could cause issues with certain pre-amps? |
Check out new pics on my "virtual systems". Finally stained my Mapleshade platforms and placed them in the rack under the Exactpower and Job. Moved some equipment around. |
Merry Christmas and Happy Holidays to everyone! |
Joe, did you get my email with the three links? |
Preamp next and probably by mid year.
No plans for Mono-blocs when I last asked a month ago or so.
I would love to see an integrated with basic remote... |
From the http://jobsys.com/products.htm website:
More New Jobs are coming
We continue working on new JOB models for 2014, including a preamplifier simple solution, a mono amp more powerful and maybe even a phono stage.... Please keep visiting this website for more information |
Whats other projects does this company have rumored coming out? Preamp? Integrated? And when? Alot of buzz about this company. From reading the personal comments the Job sound or tonal quality seems to be alot like Ayre. Transparent,yet not sterile sounding. |
Well, with over 80 hours on the SR fuse in the Job I must say it definitely has taken an outstanding amplifier to another level. More air and transparency. More of a cleaner sound with lowering of the noise floor which is making even more information coming out of a blacker background. On live jazz recordings for example, I can hear more of the audience, tinkling of glasses, applause, that sort of thing. Now, someone may ask why the hell would you want to hear more of the crowd? Obviously that's not what I'm getting at. With these fuses I feel more "immersed" in the crowd, like I'm more THERE and the audience is more around ME. Midrange is warmer and more rich. Soundstage is wider and I hear more depth. It's much easier to follow instruments in the back row of the orchestra. Everything just sounds cleaner.
As I told my friend Bigshutterbug, I first placed the fuse with the type reading left to right. Meaning, while looking at the rear of the amp and pulling the fuse drawer TOWARDS YOU, the type read left to right, like normal. After listening, I reversed the direction. This resulted in what appeared to be less natural "shimmer" on cymbals and somewhat brighter overall sound. Midrange wasn't as warm. Going back to original direction made midrange more real and highs sounded less irritating. However, I wonder if SR has all of their fuses in the same direction when sending the high voltage through at the factory. If anyone has found different results regarding the direction in their systems, please let me know. |
Having fun is what it's all about. Congratulations! It makes me happy to see you having a blast! |
Yes you did mention that Joe. Lol. If they weren't so expensive I would try them. I need two so I went with the SR.
Yes,I'm having a lot of fun! Tomorrow is my last day of work then I'm off for 17 days! During that time, I have my new fuses and vibration platforms/points to try out. I hope we get a bad storm and I get snowed in for a couple of days so I can play with my new toys. God, I feel like a little kid. |
I told you! I think the Audio Magic is even better. :) |
Alright, I know I said I'd wait but I have to chime in. I only have 15 hours on the Synergistic fuse but already, ALREADY I hear more air and more transparency. I feel as though the noise floor dropped even further because I hear more subtle nuances emerging from a blacker background. I will install my second fuse in my dac and repeat the process. I have two sets of Mapleshade vibration control systems (isoblocks, maple platform, and brass ponts). After the fuses, I will first put one "system" under the Exactpower voltage regulator and then under the Job. I want to stain the platforms first. |
:)
Looks like someone is having fun! |
Last night I put the Synergistic fuse in the 225. I will have the amp on for at least 50 hours, then switch the direction of the fuse and see which I prefer (if I can tell). Once that is determined I will place the Job on my Mapleshade system of Isoblocks, maple block and points that greeted me at my front door this afternoon.........oh boy oh boy oh boy oh boy oh boy oh boy. |

Hi Joe, yeah if I didn't have the Bent I would jump on the preamp in a second. Who knows Joe, I may do it anyway just to compare and sell whichever I don't want. It's win/win for me because the Bent is a very desirable piece so I know I won't loose any money there, and considering the very favorable opinion of Job within the community one could expect to get 80-90% of their money back if they chose to sell the Job preamp.
To anyone on the fence about trying this amp, I will say with no reservations whatsoever that the Job 225 is the find of my lifetime. I have never heard a component, anywhere, that scores higher on cost-to-performance than the Job 225. |
I've said this before but here it is again: every time I listen to this amp, I shake my head in disbelief to the sound I'm getting. Hi Devilboy, I feel the same way. I've been through a lot of amps in my time. I still fantasize about some of the new more expensive latest and greatest amps but I ALWAYS come back to the Job 225 for it's amazing performance and natural sound. It's just so darn satisfying. When the Job preamp comes out, I am buying it. In fact, I will buy EVERY Job produce they release. Job is a supreme value in my mind. Thank you Job Electronics for an amazing product. |
I felt exactly the same immediately after my purchase of the 225 due to not owning a preamp. However, I was fortunate enough to have been blessed with a Bent TAP-X falling into my lap......for the second time. That said, I think I would love to have the integrated, or even still, have a listen to the preamp when it comes out. I've had some serious listening sessions in the last three days and I've come to a point where I think my 225 has reached its "breaking in" point. It always sounded amazing but I think a few days ago it hit the mark for final break in. I've said this before but here it is again: every time I listen to this amp, I shake my head in disbelief to the sound I'm getting. |
Rather than a Preamp, i wish Job would make an integrated. |
Klh007, so did you get a chance to hear the Job driving the 3.7s and the Pendragons? I'm curious to know how it did with the Maggies. Also, because of the Job's incredibly high gain, I have a feeling the volume knob didn't go too high while driving the Pendragons which I think are pretty sensitive, if I can remember. |
I just ordered Synergistic fuses for my 225 and my dac. Finally. |
Hahahahaah.
George, you never stop do you? You have ben trying to dimish this amp from day 1 based on just a picture of the innards. When that failed and the feedback has been overwhelmingly good, you now say that it cant power anything but benign loads.
Why do you fear this $1,700 amp so much? Is it because you perceive a commercial threat?
Dont worry, there is space for many kinds of products out there and all kinds of competing philosphies. Nothing is right for everyone, but many seem to be well satisfied with the outstanding value proposition they get with this amp.
Just let it be. It's a useless battle to wage, as the amp is still selling like hotcakes where demand still outstrips supply. No amount of speculation will change that. |
Quote from the Jazz Times review:Speakers can take up to several hundred hours of playing time to begin sounding their best. However, as soon as I had the Nines up and running, I had to call DeVore to tell him that these were the most outstanding speakers I’d ever heard in my home, a judgment made while listening with a modest nine-watt amplifier.Quote:
From this review:
http://jazztimes.com/articles/18496-devore-fidelity-the-nines-loudspeaker
Cheers George |
I have no idea what the "quoted 9 watt amp" was, nor have I ever listened to the Nines with anything less than a 55 watt tube amp, that weighed 65 lbs. I also used a 100 watt hybrid amp for a while and the Job was simply better in vitually every parameter than both amps. The tubed amp btw cost $1k more than the Job.
The dealer where I purchased the Nines recommended at least 28 watts to drive them, since we both like to listen to rock and orchestral music at fairly high listening levels. I am skeptical that 9 watts would be enough power for my listening tastes! Although the Nines are easy to drive, they do sound much better with quality electronics, e.g., Leben, Shindo and now Job.
As an added bonus,the Job is the only amp that I have owned/auditioned in my home in the last 10 years, where there is no transformer hum! There is DC in my lines that has caused various amounts of hum, depending on which amp I was using, but the Job is totally silent! |
No I have not heard them, and agree they may sound great on the Devore speakers as they are reviewed as being a very easy load and can be driven by a "quoted" 9 watt amp.
On another forum a member measured the heat sink temp at 60c on a 23c day driving a pair Lennahan Audio ML-1 book shelf speakers at moderate level.
http://www.lenehanaudio.com.au/index.php/products/ml1-loudspeakers/ml1-measurements.html
They have an impedance curve and phase plot that is quite easy to drive, they are a little low in efficiency, but not abnormal for a book shelf. Recommended amps are from 20-300w for this speaker, not as easy as the Devores but not very difficult either.
This kind of tested heatsink temp on a coolish day is too high, and the chassis forms part of the heatsink, which means the internal temp will be high also. Any increase in the ambient temp will increase the heatsink/chassis by the same amount. Electronics specifically capacitors won't like this kind of temp, and the junction of the output transistors will be even higher.
Cheers George |
George, just wondering if u had a chance to hear the 225 and if so, with what speakers? Mine are 6 ohm and 89 db and it's the best amp they've ever had on them. I even prefer the 22t over the E.A.R. 890 I had (which was the midrange king). Not saying my speakers are a difficult load, just saying. |
Sorry to come back again Genjamon, but you don't get it.
With your very easy to drive speakers, this amp may I admit sound very good.
I'm referring to those here and on other forums that spruik that this amp can do wonders on speakers that are harder to drive than yours, which is simply not the case.
And potential customers need to know this and take it into consideration before buying one.
Cheers George |
Yes, yes, we get it. Job is a 100wpc amplifier with a transformer size that limits it's power output. The manufacturer skimped a bit in that area to match production to an inexpensive price point. Not a surprise to anyone who has looked into it a bit. Soooo, you have to match well with speaker power demands. Isn't this the same with any amp? I don't think anyone has claimed this amp defies the laws of physics...
Within those limits, however... |
Grk: "Hi,I'm using the JOB to power Devore Nines and it is the most dynamic and best bass that I have heard from these speakers!"
Hardly supprising, as most of the Devor range are very easy loads, that remains at or above 8ohms, and don't tax the amps at all, easily driven by 9 watts so Jazz Times say
From Stereo living:
"The Nines are among our best selling products. Needless to say they sound great but beyond that they are easily driven by any tube amplifier in our store. They will sound wonderful with an entry level tube integrated"
From Jazz Times:
"I had to call DeVore to tell him that these were the most outstanding speakers I’d ever heard in my home, a judgment made while listening with a modest nine-watt amplifier."
Cheers George |
I believe the Devore speakers sound amazing with the Job 225. It's a combo that I need to hear. I never would have thought my TAD CR-1's would work well, but I have to admit they sound superb with the Job. I am not one to play very loud and don't really push any of my amps. The Job is in my top 3 with only a Dartzeel 108 and CJ ART amps bettering it. I feel that strongly about the Job. |
"Genjamon: Also, it's true the Maggie's would be a hard load."
The Magie 3.7 is from what I have found out is very similar to the impedance of the 3.6. That is it's a benign 4ohm load, that even a good reciever will drive.
From Absolute Sounds:
"The speaker’s impedance is 4 ohms. Its load is essentially a resistive one; therefore, driving it doesn’t pose the loading problems"

Hi,
I'm using the JOB to power Devore Nines and it is the most dynamic and best bass that I have heard from these speakers! Great soundstaging and imaging as well. I can imagine that paired with the Orangutans, these qualities would be even greater given that the O's are much more efficient.
Also, I am using bananas on the amp, without any problems. Because of some space constraints and that my speaker cables are a bit stiff, bananas fit better.

Hey, I have a Job too and am pretty happy with it. Also, it's true the Maggie's would be a hard load, and he admitted he wasn't able to do an apples to apples comparison with the others due to grounding/noise issues with DAC direct. He also admitted he needs to do more listening and will be doing a more thorough follow up. It was also clearly the most inexpensive amp in the comparison by a wide margin and held its own in some ways, even in an unfair speaker matching. I think I recall that he has Devore Orangutan speakers, and I'd be really curious about that pairing.
All that said, I could see his point that speed might be the Job's biggest strength, and not as much tone density. In my own system, I run a different model of Tekton speaker and get my tone from a fine tube preamp and an analog sounding NOS DAC.
In my opinion, the Job doesn't have to be universally perfect to still be a grand bargain. And what it does well it does really well. I just get tired with the back and forth on forums of best amp ever vs. hyped up flawed design. Seems worth characterizing the Job's strengths and letting people know about some ares that aren't quite as strong so they can make educated choices about whether to try it or what other components might help complement its character. |
We still stand by our opinion that it's a stellar performer, playing well above its price point. Value is good but ultimate performance is more important. It's one reviewers opinion, and only that. Agree! Never make purchasing decision based on a professional or amateur review. I would never expect the Job to drive Magnepan speakers This is why I'm surprise it can drive a TAD CR-1. |
I and many friends have the Job 225. We still stand by our opinion that it's a stellar performer, playing well above its price point. It's one reviewers opinion, and only that. I would never expect the Job to drive Magnepan speakers. It's a wonderful amp and should be seriously considered by someone who likes a three dimensional sound stage, articulate bass, great separation and a slightly sweet natural tone with great vocals. |
Looks like Part Time Audiophile just posted a very interesting amp shoot out with the Job up against Pass Labs, SIT, Red Wine Audio, Odyssey, Merril Veritas (Ncore 1200), and Vitus. Speakers were Maggie 3.7's and Tekton SEAS Pendragons.
Job didn't fare as well as I would have thought given my own experience head to head with my Ncore 400's.
Sounds eerily similar to the listening session Klh007 mentioned a while back. He never got back to this thread with impressions, but I wonder if he was over for one of the listening sessions part of this shoot out. |
