JOB 225 2-channel Power Amplifier ... update ...

Hi All. Selling my JOB Pre2 and 225 pair if anyone is interested. I love how they sound, but have got into another hobby and since I bought this most recently, I'll miss it the least of the HiFi gear I have. They are in 'As new' condition and run on 240V AC electrical outlets (UK, Australia etc). EU style power cables are included. I'll post it in the classifieds section very soon.
 
There is a for sale thread near the end of the list of threads. Most people looking at used equipment would look there so your Job equipment would probably be seen better in that section of the forum.

I have found it is usually best to put an asking price and maybe a photo or two, or three :)....
 
Bought myself a Christmas present - JOB 225, to be used with STP-SE. Initial impression is that I can now hear more details, and the bass is significantly improved - compared to the inexpensive 300B SET tube amp I was using.

The higher gain requires me to use even lower volume steps of the STP-SE. I have also experienced the degradation below volume 7 of STP-SE as Joe mentioned in another thread.
 
Congratulations!

From 7-8, everything snaps right into focus and just opens up. Both pieces are exceptional, in my opinion, and together make a beautiful system.

Vocals are outstanding with lots of air and 3D. Enjoy!

Using the Rothwell attenuators between the STP-SE and the Job 225 helps quite a bit. It gives a -10 DB on the RCA inputs on the amplifier allowing for a little more control and range on the volume control of the W4S. They worked great for me. I actually have a set in the box with my backup cables in case they are ever needed.

I used these with the STP-SE and the Job 225 when I had both a while back. They really helped a lot.
 
This amp is one that I learned of only through audio Web sites. Been using one about a week. Preamp is passive/active (no gain in either mode) Schitt Saga with 6sn7 and resister switched volume control. It is a very nice sounding and relatively affordable combo.The sound of instruments timbre is what I think the 225 amp does best. It has good detail and bass, but my Rega elicit integrated (2nd version) edges it out on bass. The sound of piano, violin, acoustic guitar and vocals is spot on with the Job 225, dispelling any hardness, harshness or etch. The overall sonic picture is somewhere between B & K st 1400 and Pass labs Aleph 30 amps I've owned, if that makes any sense.....all 3 are well regarded Mos-fet based amps, there's something I prefer about mos-fets versus bipolar transistors, maybe more "tube" like?
It's a really nice sounding amp for the money. The term "giant killer" gets thrown around so much that after some time in the hobby one kind of gets anesthetized and wary of it. I wasn't expecting a 1700 dollar miracle when I ordered the Job, only to get a nice sounding, musical Mos-fet amp, and I think the Job 225 certainly is.
 
Welcome to the forum Holler55, thank you for joining.



I totally agree with you. I have the Job INTegrated and absolutely love it. I often think about the Job monos and love the musicality of my integrated as long as it's fed a good digital signal.

I agree, the Job 225 was a really nice sounding amp! Unfortunately I was at my experimental stage when I first got back into this crazy hobby. Therefore I moved on to other amps. I would still rank it very high on the amps I have owned... maybe third... the classic ARC tube amp I have is probably better.... and the First Watt is by far my favorite...

I never got a chance to listen to the Job on my MC speakers. I had KEF LS50's at the time.

The First Watt is low powered ultra sound quality amp... so to even mention the Job in the same sentence says a lot to me.

Monos are similar sound but much more power reserve.

Had em on demo for a month with the 225 a year or so ago.

I own both but have never done a direct comparison. The Job, which I have owned for over 3 years, hasn't been hooked up in quite a while. I have intended to try it on the Spatial's but never got around to it as it would involve swapping out IC's on both the amps and the subs using adaptors. I just haven't had the urge to get behind that rack and make all the wire swaps. When paired with the right speaker the Job punches many times above it's price range. If I pull the Spatial's out for the upgrade then I may do the swap out then. I probably out to just put the Job up for sale and let someone else enjoy it.
 
Thanks Jack. Yes, I was thinking of the Job for the Spatial as well. The TM upgrade for the Spatials sounds very lucrative; I wrote to Clayton but didn't hear back. What preamp did you use with the Job ? It seems to have a very high gain of 35db.

I wrote to Clayton too and also didn't hear back. Apparently the only way to get a response from him right now is to call him. The upgrade from the the M3 Turbo S to the Triode Master is supposed to be roughly the difference in the list price and involves the upgrade of the compression driver, changing the wiring to Dueland, changing the woofer wiring from parallel to series and adjusting the parts in the crossover. There may also be the option of changing everything but the woofer wiring so that they stay at 4 ohms which should be better for SS amp users. There is a member on AC that knows Clayton that sent his back last week for the change to TM and will initially be using his LIO. He is going to let me know what he thinks before he decides to buy tube amps and just use the LIO as a preamp. Also Gopher(Fred) from Lampi has owned the M3 Turbo S's for a while and he is going to spend three days with the TM and the ZOTL 40 at Axpona so maybe he will give us an impression of the difference.

As to the preamp for the Job 225, I bought a used W4S STP-SE to use with it and it is a great pairing and much more flexible than the Job preamp. In fact the STP-SE sounds great with every amp I tried it with. Something like the Hattor or the Luminous Audio should also work well. Even one of the new zero gain Schitt preamps should work. The lowest active preamp I had before the W4S was 8db gain and it was too much. You can cheat the process with buying a pair of Rothwell attenuators and lower the gain of the preamp by 10 db. I have a set of both SE and XLR and have heard no difference from inserting them.
 
Jack, looks like I should first get the TM upgrade before deciding on the amp. Lot of folks (including Clayton) swear by the ZOTL 40 is a great match for the Spatial. Maybe the TM + ZOTL40 will be a killer combo. Please let me know when you hear back from the AC member (I actually posted there on the TM thread as well).
 
Dev

I hope the second option becomes available to make all the TM changes but leave the woofers in parallel wiring for 4 ohms. My Spatial's are in the Family Room which is 22' x 28' x 10' and opens into the Kitchen, Dining Room and Foyer. It would take a tube amp the size of a space heater to power them in that space and the temperature today was 87 degrees in April. Plus I don't want tube amps out in that space. Clayton shows up to this weekend with Red Dragon amps and mine sound just fine with the Nord's or the Nuprime ST-10. That high sensitivity spec he shows is only for the mid-range up. From my experience from trying them with tubes and SS showed me that regardless of the specs they need power to have any sort of bottom end. If you like the sound you are getting now and just want to take advantage of the better compression driver and wiring then wait for him to offer that upgrade. If you want to migrate to tubes then the TM upgrade is for you.
 
With the Job you should grab a pair of the Rothwell's. I used them when I had a Job. It helped letting me have a bit more volume control from my preamp. I agree with Jack, you cannot beat the Wyred 4 Sound STP-SE.
 
Jack, thanks. Ahh...I see what you are saying - so the two woofers of 8Ohms each are wired in series in TM (and parallel otherwise) ? The Nords sounds very good with enough drive, details and dynamics, I just wish the mids are a bit flesh out. I don't how much improvements are there with M35 over the M25 driver. If I get the ZOTL40, should the TM help ?

Now that you have done the DAC upgrade you need to do the preamp upgrade. Maybe he has a Level 2 at the shop that he will let you try against the base model. If Srajen is right then you will be hooked again.
