Third GB - MAYA advanced R-2R logarithmic ladded

[aradan]

Hi Tbibi,

I have a question what type of encoder should be used for maya.

I know you have it bundeled but I was thinking to replace.it with metallic body encoder from alps if you wont mind.


What do you think about this one:

Encoder provided with MAYA is metal too and quite reliable, as I had zero issues so far.

If you are looking for something different, this encoder was tested and is working fine.

The ALPS mentioned by you will not work and beside this have only 15 impulses/360degree.

Preamp With Maya R2-R finished

Outline of my pre-amp: Maya R2R volume controller/ 4 input selector, with display. After the volume controller, I use the AMB Alpha 24 line amp, powered by AMB Sigma 25 / 26 PSU's with AMB Sigma 78 / 79 low noise regulators. Chassis, the Modushop slimline U3 (120mm height/4.7").

As I have plenty of space left inside the chassis, I will later integrate the AMB M3 headphone amplifier in my preamp with variable gain (2-17).

My preamp matches nicely with my Beta 24 power amp and my Music Streamer (Audiolinux OS+HQ-Player). Here are a number photo's, enjoy! Changes in sound quality with this preamp are almost non-detectable for me. It may be that the SQ is a bit brighter compared to the preamp part of my RME ADI-2 Dac.

More info and photo's on my build can be found here: AMB Laboratories DIY Audio Forums • View topic - α24 with M3 preamp built log&Q's

HI

Do anyone have a front panel cad with correct dimensions for the Oled that I could use as a start when making the front panel?

Best regards

Hi PieterPiet, on one of your pictures, it looks like the Bluetooth receiver is inside the enclosure. Does that still work well? Doesn't the enclosure block the signal?

Hi Maarten, i dont have a BT module yet. If someone knows a simple/auto pairing module wit good dac, i'd like to know it.
