Again this is opinion but I do own all,the stuff but I do not review items.

 

No, I like my M7 w/ fully-loaded OR5 and DACLadder mod.  I am just trying to learn something between what seems/seemed to be at odds with each other in a way that I couldn't resolve myself.  Thanks for the response.

Quite easy to explain:

 

  1. It's all relative in comparison to other DACs.

(...)

Thank you for the response.  I think there was some nuance that I was missing, regarding your statements that was causing the confusion.  I think I get it now--it's not absolutes, but shades of grey you're talking about.

post #1953 of 2366

Yes, it's almost always relatives, not necessarily absolutes. I try to establish relatives and imply or sometimes directly state my preferences in absolute terms.

 

But it's not necessarily shades of grey, it's more comparative like X > Y and Y > B. If there's anything I tend to be guilty of, it's being too black and white in terms of relative comparisons. I tend have a bad tendency of stating A = great and B = poo because A > B, and not explaining current magnification level or context.

Purrin is over-sensitised to subtleties. ;)

Are you saying it must be used with a really good converter - or are you saying it "must" be used with a OR5 or ap1/pp?

post #1956 of 2366
Neither as music ,headphones and desires all mAtter. For me I like hyper details so I need an usb converter to calm down the heavy impact. But a bass head would be in heaven. It's all a good by me. Sound wise I like it better than the old pwd for sure and a mytek just gives me a headache .

if you use the i2s input, does it  clock anything? Has anyone replaced the clock for a better one?

 

I asked king-wa if better clocks could be changed and he said there might be better ones.

 

Audio-GD use the following clock

 

Frequency Accuracy:  +/- 0.3ppm Max
Phase noise :  -125 dBc/1KHz @10MHz

 

I looked upon better ones and I found one for 60 USD lol  (TCVCXO)   

Frequency Accuracy:  +/-50ppb ( billion )
Phase noise :  -138 dBc/1Khz @10Mhz

 

bleh I'm not writing the specs down correctly http://www.mouser.com/catalog/specsheets/Pletronics_OeD4204_customer%5B1%5D.pdf

 

Maybe TCVCXO are not meant to be used in this aplication to technical for me :P

Yeah, the DAC chip.  Out cold.  :wink:

 

Actually, the whole point of the I2S input is that it uses the source clock only in transmission, so that there shouldn't any signal timing jitter in theory.  Just maybe cable impedance and reflected waveform degradation.

Subtleties sensitive?  Now that's funny.  You mean like nuance obsessive?  :biggrin:

Basically, yes. It is something I came to understand about my own experiences through unexpected means. I'll write about it some day.

Here is my observation as I do not know theory but do have ears and a brain to hear changes.
Using the hdmi from the PWT. By OS audio to the hdmi interface from dac leader does not yield the same as from a ap1 /pp over spidif and ninth same as hdmi out of the offramp.
Although they both work well the inputs do spund very different . With the offramp hdmi sounding best to me. And dead lastmisnthebps audio PWT .

Now this is with the the M7 as. DAC. Now using the usb new drivers the bass is still,not as tight as the other two and still better than the PWT . Now the PWT does not have a clock inside maybe this is causing it to be worse .

Yes, please do.  It just boggles the mind with all the tacit implications...  :wink:

post #1963 of 2366
I feel currawong has very good ears and I have always found his info very usfull even if I sometimes disagree a little. He is strait up honest as purrin is too but it could be he means he us picky . I find myself going in that direction sometimes looking for a point to make when the point is very small. I could be wrong about what he means but he is an admin and must read more than anyone here about people's post,s. I am sure I drive him crazy at times and remain respectfull of his choices agin even if I may disagree. Purrin has Said some stuff about a couple of dacs I would to discuss this on the phone but so far no responce .

Both Currawong and Purrin have great ears.  I don't think there has been a occasion in which my own ears did not verify, either in part or in whole, a claim or opinion they have made about a piece of equipment that I happen to own although I don't think the M7's character is as easily identifiable through its usb input as Purrin states.  I bought the M7 after reading Currawong's review. I bought a HDMI I2s board for the M7 and I will buy a Offramp after reading what Purrin had to say.

Great thread, lots to learn from many knowledgeable contributors, so a big thanks to you! :cool: Im sitting on the fence for EA OR5 which Steve Nugent told would probably get discounted when the OR6 gets ready in 4-5 months time. In the meantime I have come across the (not so new) SOtM USB PCIe card which Im considering for my HTPC. Have anyone experience with it combined with M7, or heard of people that have? I read somewhere that it wasn't compatible with the OR5, which I find strange ( if I understand correctly the SOtM is just a USB host card with noise reduction)..
