  1. Selamat petang. I've tried a few class D amps...but not those. There are the much newer TPA32xx amps which only require a single voltage rail.
  2. Its even more difficult if the USB DAC is USB powered. I'm using a USB DAC (usb powered). The output stage of the DAC has been rebuilt and its is powered seprately by linear supply with 2200uF close to the input. This way its a winner. Please note that a 2200uF of any sort on the power rails is not inline with USB standards.
  3. Thank you for the feedback. The unit that i got has about 15db worth of gain. It played havoc with the 32db gain of the power amp. With the amplifier gain setting changed to 26db the overall setup had an overall volume curve that was still too sensitive. I'm a toob noob so when i have some free time i might look into how i can lower the gain without cropping the input. It also has an inverted output signal from its signal drive stage. Things i didnt know before jumping in.
  4. What sort of gain do you build your tube stages with ?
  5. For a little while it was: tube pre - class d power. Now its back to: passive attenuator (shunt) - class d power. The class d amp is a modified TPA3116. The tube pre was a budget item with an online following on some forums (i am aware that budget and tubes dont always go together). FX audio tube 01 with a pair of GE JAN5654w in place of the stock 6J1 items. It sounded pretty good stock and surprisingly good when powered with a recaped GME linear supply. One clear advantage of the hybrid setup would be a slightly richer tone. With the current system, i have a preference for an attenuator (and series resistor) at the input of the amp. I totally agree! Class D brought me back to the hobby. They can also image really well.
  6. The new speakers are looking good Dave.
  7. Looks good. What sorta spikes did you use for the build ?
  8. I suppose in "trek" parlance, the reference to an externally shorted resistor is not in full light of the borg intention and welcome address... We are the Borg. Lower your shields and surrender your ships. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service us. Resistance is futile Unlike the resistor, the "crew" were never shorted. The nanoprobes screwed them over. IMO, the borg intention would be better illustrated with additional electron pathways (nullifying the resistance) and borg paraphernalia in and out of the resistor body. My apologies to AJ. I do like the shirt (its a nice shirt) and i will not be adding to the thread detour.
  9. In the t-shirt pic... the resistance has been shorted.
  10. Oh cool. I’ll have a look see. 👍🏼
  11. Cheers mwhouston, Does the UI work well with mobile devices ? In my work area i'm using a PC.. no issue with the layout. But in my main rig (and using a phone) i found 4.3 to be a bit tricky to use.
  12. I'm still using 3.81 - 3.84 for the voicing of my setups.
  13. This puts it nicely. I'm not a fan of the new star wars. Sorta like new top gear vs old top gear.
