DAC AD1862: Almost THT, I2S input, NOS, R-2R

[altor]

pcm63-k virus spread... all ad1862 traitors,

Some people think that PCM63 is better than AD1862, some think the opposite.

P.S. I belong to the second

 

[diyiggy]

Ahaha...yes...different chips and personal taste... I imputed for the joke cause Nixie recieved a full bag of pcm63 k...ahaha.

 

[Brijac]

I purchased 4 so i have extra two if they fail on me when i'm retired (probs will be unobtanium then) 😅
Yeah tastes are simply what defines finese of good sound, and we can all agree, all these sound good, it's the finese that makes us choose one or the other.

Ahaha...yes...different chips and personal taste...

Of course, some like blonde girls, others like brunettes.
I even know people who like NOS TDA1543...

 

[diyiggy]

Has someone thougth to send a pair to Miro ?

Can live with either and both in the same time if I have to sacrifice myself for the cause but certainly not with a TDA1543.

Damn, i thought miro has a pair. My budget recoveres in january (december drains me, 23 kids to get presents for, and a few elderly), and it can be a late new years present

 

[diyiggy]

Ah no that is Altor who talked about that. You have several spouses blond and brunettes then

Me if I had 23 kids I would sold one or two to get a TDA1541 double crown...but I keep my pair of course.

Nah, few of mine, friends and relatives ones 😅 I think i'm done with kids, perhaps one more, should be enough to pay for them crowns 😂

 

[diyiggy]

Put them in the basement to make carpets...audio became expensive!

 

[Brijac]

Oh the youngest is actually costing me a lot in equipment, quite a destructive little fella 😅

 

[diyiggy]

Could had be worse...imagine being Greta Thunberg's father...

Guys could we put a relay attenuator on the output of the DAC (1862). 50k with fairly flat impedance apparently.

 

[diyiggy]

tried with another dacs... soundstage always suffers with passive pots... At least in my setups.

 

[jimk04]

I should add more details....I'm thinking if adding a remote relay attenuator I have here to the output of one of my Miro DACs to use it conveniently with my TV. It will then go into a Salas DCG3 set to an arbitrary level...probably about 75percent. And then the wife can alter the volume without too much fuss! So it will go through a pre amp.

I don't use premap since I make my own DACs, the output voltage is never below 4Vp-p and the output resistance is less than 50ohm, after that signal goes to the P&G of 10k and in the output stage, in this case the preamp is simply unnecessary and the whole system plays better without a preamp, and not only for me

edit; I think the catch is that I insert a low-impedance output buffer in my DACs and thus avoid another stage to the output stage. However, some amplifiers without preamps do not work well.

I tried with a low output dac (2V p-p) trough an op861 buffer. The pot was a 25K ALPS BlackBeauty (or was it a 10K...me and my memory, hum) then the amp was 100K input. Total length 75 cm.

The whole reason i've added b1k nutube was to get some more analogue sound to my purifi class d. With this dac i belive that should have that settled, and most likely i will remove it from the chain.

I have one pair Save it for the future, these converters will be no more available

Try with another buffer, for example AD815 ,I think I might test one soon.
