    Tube Amplifier Design and Rolling Tubes

    In 2024 if the end goal is to not have the tubes effect the sound of the circuit then we've defeated the purpose of using tubes at all. There are far better ways to create a transparent signal.

    Tube Amplifier Design and Rolling Tubes

    I checked out the schematic Unfortunately like most here I assume, I lack the knowledge and education to comment on how well the job was done. I think it’s a fun project and if you decide to build it, I’d follow the thread with interest. What I would find particularly interesting is the...

    RPi + CamillaDSP Tutorial

    I’m dropping the drivers into my DIY speakers this weekend and wiring everything up so it’s almost time for CDSP. Hopefully will have time next week to get things up and running. So the pressing question is pi4 vs pi5. I’m going to be running 8 channels of output. Is there any benefit to SSD or...

    Furniture maker looking for diy loudspeaker recommendations

    This would be my suggestion for the speakers. The design of the box is fairly forgiving. Just order the kit without the box obviously. With this particular design, the bigger the box, the deeper the bass. With a larger speaker cabinet, it performs best sealed (no port). I make this suggestion...

    RPi + CamillaDSP Tutorial

    I’m glad I asked because that was not the answer I was expecting. Happy to try it out and report back since you think it should work.

    Add SPDIF to Topping DM7 8-channel DAC

    Mine arrived Sunday. I waxed the walnut, but I’ve decided to put a second layer of leather on the sides because it’s gotten a little beat up during the wood finishing process. These things are going to be crazy heavy once I get all of these drivers installed.

    RPi + CamillaDSP Tutorial

    Probably an edge case scenario but I’m getting ready to embark on my CDSP journey and making appropriate plans and purchases. I noticed that WiiM has hdmi arc and a remote. My system will be pi based and I’m using Minidsp U-DIO8 for CDSP. If I use digital out on the WiiM plugged into one the...

    NAD C 298 Power Amplifier With Purifi Eigentakt Amplification

    That’s probably just a bad generalization. Very few class AB amps that produce this much power have such a low distortion profile. The other place it “can” make a difference is that a lot of AB amps can handle bursts much greater than their rated output while class D amps seem for the most part...

    Denafrips Enyo 15th

    Alvin was pretty exceptional to deal with. I have nothing but good things to say about vinshine. I have a Pontus 12 at home and an Aries at work. I like them. The Pontus is stunning and the Aries is not bad on the eyes either. They’re both very heavy all well made. The craftsmanship really is...

    Fail with Maop 11.2 matched pair

    Let's talk through the subwoofer thing when you're ready to have that talk. There are ways... The easiest would be a Y cable and carefully selected passive line level crossover (first order) and you can blend the sub in from there, but it's super situationally dependent. That will take care of...

    Fail with Maop 11.2 matched pair

    I really doubt that glass is attenuating the highs, I’d be more inclined to be believe the opposite actually. Does your listening impression match the measurements? Is whatever you’re using to measure calibrated? How do the listening impressions compare to your other build? Small sweet spot...

    A theoretical question regarding bass isolation in an apartment

    One more thing that likely goes without saying but DSP. Most subwoofers once they interact with your room are going to create great big peaks in the in room response sometimes to the tune of 20db. Taming those peaks reduces the feeling of excessive bass in the room and prevent them from being...

    A theoretical question regarding bass isolation in an apartment

    My first step would be having a dialogue with neighbor and establishing how big a problem this actually is. My second step would be decoupling the subwoofer from the floor. Doesn’t have to be expensive or exotic but we want to minimize exciting the floor and transferring that energy across to...

    Add SPDIF to Topping DM7 8-channel DAC

    Thanks for the detailed explanation. Umik-2 is likely cheaper than finding a competent audio interface with digital output so, that makes things easier.

    Add SPDIF to Topping DM7 8-channel DAC

    Are you using the digital inputs on the U-DIO8? If not l, how are you making your measurements and do you have issues with the recording interface and the output interface having different clocks sources? I feel like at some point I read that was problematic in REW.

    Unifi PowerAmp UPL-Amp

    Totally, and honestly this product doesn’t interest me as much as the underlying tech does. Once Unifi establishes a use case for the the hardware someone will create a version without amplification and without the Unifi margins. I could totally see someone like WiiM integrating this tech into...
