New D3's....first impressions

Oh, it depends. I have routine visitors from I would say 20 different countries, maybe more over the period of a few months, on a continual basis. I have business relationships with manufacturers in 15-20 countries. Point being, ALL of these people that I see on a routine basis all listen to music with me. I always get to hear everyone's music. It's fascinating. I would never in a million years discover the things that I have introduced to me. I can't think of a single genre that I can't find something that I like. I really appreciate the things that I like in each genre. I also play guitar, that's probably my real music "northstar":audiophile:

Hi Bob,

What kind of music are you listening to, generally, that you prefer?

"Live in the moment"
 
Congrats Bob !! Very impressive room !!!!

Mark, thank you, it's really a "mess", there is stuff coming and going ALL the time. Much better for sound with ONE set of speakers in a room, BUT I will tell you, if you can still get killer sound, which you love and then you have 10 sets of speakers to play with, that's fun too.
 
I have a Lampi tube Dac as front end. Is that a problem for the Job, which seems not to like Tube preamps? If there is a SS preamp section between the Dac and the Job, is that enough "insulation"?

Hi Norman,

As long as the Lampi dac does not pass dc to the Job 225, you will be fine. If you have a cheap pair of speakers to test it on before going to your reference speakers, I'd recommend trying that. The Job 225 has no dc filtering and will pass dc to your speakers if present on the preamp or dac possibly ruining your speakers.

Joe,

That's really good advise, nicely worded!
 
Yes looking forward to a nice listening session !!!!since the d3's are a pipe dream for me I'm not sure I want to hear them . Lol

Hi Steve, I can see clearly now, with regard to the different Raidho models....like most speakers it's room dependent. If I had a small room I would be COMPLETELY satisfied with a a pair of C1.1 or D1's....either actually. But in a big room the D3's or even D'2 are going to just naturally sound better. On the other hand if you try to put D2's or D3's in too small of a room, you very well could end up with issues. My next C1.1's are coming within the next 2-3 weeks. I will let you know.
 
Bob, my question was more quantitative than qualitative.

Jobs' site and 6moons say that tube preamps often leak a bit of DC and the 225 does not have some component protection, presumably to preserve max dynamic range....


* Directly from the owner's manual, "the Job 225 is a DC-coupled amp without protection. If it is associated with a badly designed or defective analog preamplifier (often true for tube preamps or some 5-channel processors) the speakers could easily be damaged by DC. The Job 225 doesn't amplify DC but DC applied at the input is passed to the output."

Understood, I was preoccupied. Many of the older Goldmund amps were not very well "protected", but they sure did sound good. You just have to be careful.
 
Please tell me this is what Heaven looks like :
Um doesn't look like heave but I'll bet you it sounds better than that:exciting: When I heard the D3's they were on a Burmester stack. I just got the stitches out of my chin when it hit the floor after hearing that. :snicker:
CONGRAT's

Ha!

I am sure it sounded wonderful.

Thanks Bob,

Here is the6moons except that explains what I was fearing, It seems the new version of the 225 addresses the issue:

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]Final comments & suggestions[/FONT]: At publication time this amp sold exclusively via Amazon, only as a 117V unit andonly to US customers (even Canadian readers were refused). Job Systems also didn't publish their email to answer inquiries (the owner's manual does have it) to make pre-sales support zero. With 35dB gain and 0.75V input sensitivity, overeager volume controls and/or preamps with high gain will get loud very quickly even on standard 89dB speakers. And without a DC servo, this direct-coupled circuit won't amplify but pass on DC to the speakers. Even a superior valve preamp like my Nagra Jazz occasionally created small crinkly noises to suggest mini incidents of DC leakage when all other solid-state sources were dead quiet. One suspects a DC servo was omitted for sonic reasons but if the firm were interested to broaden the 225's appeal, one might suggest they rethink this particular feature.

Very interesting!
 
The solution:

Special Notice:
If you bought one of the first JOB225 delivered before June 25, 2013, we used in the product a ground configuration optimized for the dynamic range but which requires extreme care in selection of cables and cable path. We found out that most of our JOB friends may have difficulty installing the amplifier with the zero-noise that can be achieved. In most case the noise was not a disturbance. However with very high efficiency speakers or especially inappropriate cabling, it could become bothersome. So we proposed a modification that makes it much more buzz-immune. Note that all amplifiers delivered after June 25th are modified and all customers who want the amp to be modified can write to [email protected] to be taken care of. To answer the most usual question, we consider the moification as having an effect on sound quality quite difficult to detect.

That's very encouraging. I must buy one of these suckers to try.
 
Final point Mike and Bob:

[FONT=Arial, Helvetica, sans-serif]The JOB Amplifier is DC coupled with a new type of DC Servo Control avoiding any DC offset.
DC coupling is the only way to avoid time error in low frequencies. It avoids the usual boominess of the speakers bass response. So you get

After 24 hours of switching amps in and out, I've found that for me personally big SS state and the D3's are not my cup of tea. Give the D3's big SS power and the bass is too much for me. It's not a lack of control of the bass, just too much output. Yes, I have experimented for 10 hours straight with every possible placement option in the room etc.

What I ended up hitting the bulls eye with is the Absolare amps. You would not think that 52 Watt SET's would be an ideal match, but they are. I have them running on the 8 ohm taps and all I can say is if anyone is in the city, give me a call and come by to hear this, it's over the top. Plenty of power, TOTAL control of the bass, especially on big scale orchestra with big time bass/kettle drums etc. Total control, plenty of power....now this is heaven.....and the D3's haven't even started to break in yet.

It's funny Joe, you ended up with the CJ on your CR1's and I ended up with tubes on my D3's.....which I never ever thought I would.....go figure.
 
Bob

Mark and Mike can attest to this but once I bought the Job 225 my way of thinking was turned upside down. Then I added my Revel Studio2 and it was game over. Conventional wisdom was high power, nothing less. The Studio2 are perfect with either tbe Job225, my Dartzeel and outstandingly my GAT/ART combo.

My advice now? Try what you think will not work first. You just might find that ultimate combo.

I'll make an appointment to see you soon. I'm so excited.

That's awesome I of course wouldn't even look at anything that people say tubes won't drive.
Those amps have alot of power for SET's . I saw a turntable in the back of your room,
Can I bring albums to listen to???? Can't wait to hear these !!!!!
Get some sleep !!
