    Volume control on SMSL DAC's using MPD > ALSA > SML DAC appears not to be a standard feature

    Yeah this is the volume control "working DAC output:). In this case the SMSL Sanskrit 10-th edition MK-II. I'm looking for a new DAC and kinda like the smsl's as the price/quality is pretty outstanding I'd say. Not sure which one to choose just yet. Price range I'm looking is around €300,-...

    Volume control on SMSL DAC's using MPD > ALSA > SML DAC appears not to be a standard feature

    Thx for the quick reply. I know I can configure mixer_type "software" in mpd.conf but it isn't as smooth:) Below the out put from the commands. A bit lengthy I'm afraid.... root@vintage-audio-bussum:/# lsusb Bus 002 Device 002: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly Feiya...

    Volume control on SMSL DAC's using MPD > ALSA > SML DAC appears not to be a standard feature

    Hell Gents, I'm running a raspberry Pi4b with usb dac, the SMSL Sanskrit 10-edition MK-II and soemtimes the MK-III. I recently played around with the D6S from SMSL used by a freind of mine. I noticed the volume and mute function could not be controlled using alsa as this specifci interface was...

    Raspberry pi 4b with dietpi, mpd, upmpdcli, alsa and USB dac

    Hello there, I'm looking for improvements on my current setup. I'm using the pi as a streamer for Qobuz. The smsl sanskrit 10-edition MK-III is outputting to my diy wolverine amp which drives 2 Kef reference Model III's from the nineties. To my ears the sound is really good and I'm looking for...

    The PM665-VXi refurbish project

    Hello Gents,....got my hands on PM665-VXi from Romania. Planning to refurbish it just like 640-VXi and 645-VXi. Threads and pics can by found on this sub-forum. Measured the DC offset and Idle current and they were a bit off. Luckily you can adjust both DC and Idle on it so after adjustments I...

    Best digital audio source: raspberry Pi vs Android phone/iPhone/ipad

    Ok..thx for the advice. I'm new to "roomEQ". Buyuing the mic is the easiest of course but what software do I install on the rpi4 running volumio. Ireckon its a seperate install next to volumio or something...and how do I configure it:)

    Best digital audio source: raspberry Pi vs Android phone/iPhone/ipad

    Morning Gents, I hope a not to old thread for some directives. I've been watching Hans Beekhuyzen a lot and wheter or not you are a fan doesn't matter. I've learned a lot and includes the stuff I found here on the forum as well:)....Having said that I'm running a RPI-4 with an IFI 5 volt low...

    Kef Q65.2 tweeter repair and temp replacement with Kef Q5's

    Update: After a couple of weeks listening to the repaired Kef Q65.2 suddenly the new Denon PMA-800NE driving the speakers went into some sort of "safe modus" while producing a very distorted output to the speakers. A red led also come on. Also the repaired tweeter went south again. All in all...

    PM645 VXi with Fast and soft recovery rectifier diodes

    Thx gents for the info.....one small question regarding noise. When I don't play anything, no music, no nothing and with volume to minimum...I hear a a very soft "sssssssssss" through the speaker only audible with me ear very close to the speaker. When I turn up the volume to maximum,..again...

    PM645 VXi with Fast and soft recovery rectifier diodes

    Gents,...thx for the insights...much obliged. @solderdue...read your snubber article. Learnt a few things:).....The amp sounds really good so probsbly no need to add the resistor in series with secondary mains capacitor (c35)

    PM645 VXi with Fast and soft recovery rectifier diodes

    This is the transformer with rectifier scheme and the small capacitors. Secondary AC is 74 volt (2 x37) DC unloaded is +48, -48 volt I don't see the resistors vor de current limit to the 0,01 uF (10nF) capacitors. Is this more or less trial and error or could also start using 82R for instance?

    PM645 VXi with Fast and soft recovery rectifier diodes

    thx ...well i dont have a receiver as Im only using web radio's. I thought the soft recovery diodes also reduced the ringing or is it both the small caps ND the soft recovery diodes adding to that? reg willem

    PM645 VXi with Fast and soft recovery rectifier diodes

    Or do you mean the big 10.000 uF / 63 volts caps?..I've undestood you cant rais them by too much as the surge current when firing up the amp might take too long too fill them which could be lead to damage to eith the transformer or other things....

    PM645 VXi with Fast and soft recovery rectifier diodes

    Now thats an answer with solid info!! I indeed read about the low frequency (ie: 50/60hz) is a walk in the park fro every diode. They are in now so it cant hurt I guess. The small capacitors around the diodes are 0.01 uF. To what value could / should I raise them? reg willem

    PM645 VXi with Fast and soft recovery rectifier diodes

    Hello Gents, I replaced the rectifier diodes with these ones. Don't know whether I could hear the difference. I doubt it to be honest but while reaplacing all the caps I thought I'd give it a go. ON SEMICONDUCTOR RHRP860 Fast / Ultrafast Diode, Soft, 600 V, 8 A, Single, 2.1 V, 35 ns, 100 A...
