Thread Starter 

I'll be interested in hearing what you think. Part of my issue may just be A/B-ing the M&M with the MJ&G.  I've been listening to my HD650 with the M&M at work for a while now--and I love it--I think I've adjusted to the sound.

Thanks for the opinion.  I'm keeping my expectations at a realistic level and hoping to be pleasantly surprised.  There are tradeoff's and in this case it's cash. Not Johnny, although I will play "When the Man Comes Around".

Do you have actual cable or is it satellite? If it's cable, I'd suggest you try isolating the cable connection to the cable box with something like the Jensen VRD-1FF. The audio transformers they use in those cheap audio ground loop isolators are pretty crappy. The most common cause for the noise you're getting is due to the cable company's lines being tied to a separate earth ground. And in those instances, the best way to isolate is to isolate the cable connection to the cable box.

 

Whichever way you choose, good luck!

... It reconditions and regenerates the AC wave form ...

I would think you would need something like this to regenerate the AC wave form: http://www.psaudio.com/shop/p3-power-plant/

I am very found of my Furman.


I'm sure you are and I wasn't questioning the qualifications of Furman.

I was just asking for confirmation that the AC-215a regenerates the AC wave form.

Perhaps I went a bit too far using "regenerates".  No, change that,  I went too far.

Let's go with sophisticated process to "condition" the AC .

 

Their trade process is "Lift"...

No problem putting it on the bottom of the stack.

A quick look of the specs and it will fit perfectly.

Both are 5" wide.  smile.gif

 

I've had mine a couple months for my Lyr.

As a generalization, tubes are more sensitive than SS.

 

I do not hear any distortion / noise whatsoever.

So in that case, it does a great job isolating and conditioning the power.

 

The combined rating of both outlets is 10A RMS.

The Magni is a fraction of that at 4W.  There is a temptation to 

hang a plain power strip off one of the AC-215a outlets.

 

This could (would) defeat any benefits from the conditioner.

A spinning hard drive is an example.  This is the

same as having a large fan on the same house circuit as your audio gear.

Isolation is the key word.

Ok,  I'm not trying to be Mr. Furman here.... because I'll get myself in all kinds of trouble with my qualifications. smile.gif

 

Here's the data sheet:  http://www.furmansound.com/pdf/datasheets/Furman_AC215A_datasheet.pdf

(I hadn't read it until now)

 

It says zero ground contamination.  Is this standard for all surge suppressors?

After reading many of the issues in the thread, that might be helpful.

The conditioning is "Linear Filtering".   Is this a standard process?

I'm making one more post because I've never had 4 in a row.

Thanks. I thought about this as I do have actual cable not satellite but I am still getting the buzzing/static when using RCA out of my bluray player without even playing a disc, just with the bluray powered on.  I will look into the jensen as well if the ground loop isolater doesn't work. 

post #1044 of 2152

ok did a little more research looks like problem might be that I am operating with two grounds essentially.  The cable box going to my powerstrip is grounded to AC outlet and then when I connect it via RCA to my magni, it is also being grounded via the wall wart?  Or is this not possible since the magni wart is only 2 prong? I tried plugging both magni and cable box into same power strip and no difference. I will try plugging cablebox straight into the wall and not a strip.

I'm trying to decide between the magni and the e09k for my dt-770 Pros (250ohm). Any major differences between the two? I definitely like the E09K because of the pre outs on the back for my speakers but someone recommended that I inquire about this one as well so I'm doing just that. 

If you have experience with both of them, which would you recommend and why?

There won't be a big difference between the two. Maybe more so on paper and measurements etc. I have both (well, the E9). The Magni is a bit more uncolored and transparent. It will be better for more headphones. The E9 I have is slightly warmer compared to the Magni. A tiny bit more "musical" or colored with the Q701, but barely audible.

 

It also depends on source too. I'm able to be more easily tell the difference between all my sources with the Magni. I have no clue why it's so hard with the E9.

 

The E9 is also only $90 or so. I'm sure he E9K sounds 100% the same.

 

Can't go wrong with either of them really..

Just got my Magni today and I have a quick question for other owners.  Does it usually take a few seconds for it to power on?  Or is this normal?  Thanks!
 

post #1048 of 2152
Mine doesn't come on instantly -- but maybe only a second at most?
post #1049 of 2152

Yeah mine takes a sec too must be normal.

post #1050 of 2152

exactly 5 seconds for the relay
