...So i have noticed that you guys are writing about the sound of different dac chips.
Hmm... Could it be that the slightly irritating sound these days that we hear from our audio-players is from this delta-sigma technology?
…”we hear”…hmm. I think i could first write about that.



Did you know that evolution has ”baked” our hearing depending what kind of frequency is the most important to survive? Yes, the bears, lions, other humans, all possible threat thats have been noticed by the ear and hearing.
---”We dont have any lions, and there has never been any lions where i am from”--- you say. And you are correct. So the hearing where you live, is ”modded” to other kind of threats and important frequencys that are coming somewhere else. Not from lion sneaking to get you for dinner
So-----can we say that our hearing is different and based on where you are from? Yes, there is differencies in our hearing, depending where in earth you live. Crazy, isnt it? Or maybe its just very sane. I think the hearing is very underestimated. We have the ability to hear the slightest differences in timing. We have to! if the bear or lion is attacking you!
 


I feel bad for our hearing these days, all this noise coming from everywhere 24/7. No wonder the tinnitus is so common. And this is good place and time to remind that:
TAKE CARE OF YOUR HEARING! 
You can destroy your hearing in headphones very easily. I too have slight tinnitus and it can be very annoying. You grow older, and the hearing doesnt heal.
Its gone, when its gone.



Nelson Pass has write a lot about amps, and distortion. He have found that (if i remember wrong, feel free to correct me) 1/3 of people like 2nd harmonic distortion, 1/3 like 3rd harmonic distortion and the last 1/3 doesn't  like it at all. "So we like different things, so what?"
…Well if we hear differently, doesnt it take the base off from all this, ”This is the best sounding amp/dac/speaker, its so honest”… I don't know, what is your opinion?

And i think comparing sound based on memory can be bad thing also. There is a lot of studies how sound relates to emotions and feelings. Your brain collects the sound and adds the memories and feelings to it… These can change a lot when time goes by, just like feelings.
So this hobby is very subjective, but i think many of us knows that.

But its great hobby still, isnt it! 

Hi marvey,

Nice to meet you. 
I have big respect for guys like you , who make the big effort to try out things and compare them intensivily. Your dac-compare topic in Head-fi is very informative and i want to say thanks for sharing your foundings.

I really like the way you express yourself. (and this is my serious opinion)
"Sounds like shit"  That really doesnt leave room for misunderstanding and it sure aint no politicians talk  I think it only as a good thing. I like the honest opinions.


Sound based on memory is what i have just been thinking and reading. It came in my mind when i noticed that i still have a good feeling about the sound signature of my first bought cd-player in early to mid 90`s. (Geez, where the time has gone  ) It kept me searching from internet that model of cd-player. It was Technics SL-PG590. Based on my memory it had a great sound, but it was that era of time when great things happened also. You know, you are like 14-15 years old, the girls, mopeds, good 90`s music 
I still also have Marantz cd63 MK2 KI and its not bad either. 90`s, What a golden era!


I agree with you what you say about distortion, its just i have one amp that is exception, and it doesn't have nfb., but the topology is different so i guess that the signals based on current is another thing entirely. The Audio-gd Precision 2. It clearly have quit a bit of distortion at lower levels if you look at the specs from the Audio-gd site. But the sound of that amp is very good(in my ear), and Kingwa said that it was designed to not go too low with 2nd harmonic distortion. I first had the Precision 1 but it had a buzz  noise and i did send it back. I think it wasn't ground loop problem because everything else is working and also the P2 is working fine now also.
I did once have the Audio-gd C39 pre + C10 power amp and i did find those a bit "cold and sterile" the sound reminds me of crystal glass, if that makes any sense... These newer A-gd amps have different design, and i think they are quit better than the older amp designs. The Audio-gd SA-31SE was "better" than C39+C10 but the Precision 2 is best (to my ear) from those Audio-gd offerings.
I did like the module changing thing in C39. It was like "Is it Levinson sound day?..no, not today. How about Accuphase? No, not in that mood. Well, i keep the original Marantz sound then" 


I used the C39 also as a headphone amp, it drove the headphones just fine from the XLR and RCA outputs. And that is one problem with my gear now, the P2 is so powerful that my ears are hurting in lower level output, volume level 1. Yes one.
My headphones are ATH-M50, Sony MDR-MA900, and German Maestro GMP 8.300D, and i like the Sony the most of them, but...The Sony is so sensitive that it is just too loud. I should ask Kingwa about new volume board for P2, he made me new volume board for C39 back then. Have to respect Kingwa for his customer care. I have noticed that the finishing of his products are better these days but there are still these little things like P2 volume knob is scratching in to the chassis in some position. It doesn't show but i think the knob is bit oval in shape...So-oo there is still some work to do in his QC 


About his Dacs... I had the Reference 7, the SA-2 , and Dac-19SE (full size chassis with PMD-100 + 2x BB PCM1704), and i have interesting stuff to tell about comparing those...





 

 

120V on a 4 Ohm speaker ?

  Well I used to think 45 or 50. Now it is more like 80-85.

No, it's more like 100-105 man. Well gonna be for me at least. At age 150 im still gonna look as sexy as hell as I am now.
