In celebration of successfully launching the Vintage & Precision Electrical Components Store, I am giving away my review sample of the Burson Play v1.6 to 1 person from the Hallman Labs subscribers list! I only ask that you use this device instead of trying to profit from it. No purchase is necessary for one entry […]
Preview: Rubycon Black Gate™ F vs. Nichicon Muse | XMOS Capacitor Oscilloscope and FFT Comparisons
Update 7/15/18: I just stumbled across by far the most detailed document I have ever seen on Black Gates™ and it is by Jelmax (the creators of the technology)! See the 107 page PDF here: Blackgate_Tech_Note_Compilation. Cable used between the FUN01’s Coax output and the Siglent SDS 1202X-E : […]

Preview of Hardware Reviews in Progress with sAp-10 – Balanced Headphone Amp under $200 (also the Burson Play DAC/Amp)
Finally got a balanced (XLR in) headphone amp. 2.8 MHz is native DSD64 converted by DOP (DSD over PCM). This is a picture from my phone, but I wanted to get something for readers to see on the reviews in progress between this combo and the Burson Play DAC/Amp combo. I plan to focus more […]
Old Meets New: Kenwood’s C-2 “Basic” Pre-amp gets a Burson Audio V6-OPA Facelift!
Update 6/2/18: I completed the discrete op-amp modification after I got the replacement diodes. You need to replace Diodes 11, 12, 13, & 14 with 16V Zener diodes. If you fail to do this, your op-amps will be getting +18 and -18V (36V total). This is a pretty high voltage to use on op-amps, these […]
DSC1.Difference : Update on the DSD Dedicated No-DAC (DAC)!
I have been slowly working on this project behind the scenes, without posting about it much (aside from on ComputerAudiophile.com). This is a “discrete” delta-sigma digital to-analog converter (DAC) developed by Signalyst (although, this wasn’t made by them). Their goal was to be able to convert DSD signals (digital equivalent to SACD) into analog while […]

Apologies to the Neighbors (Burson Audio’s DAC Testing Reached 100.00dB max!!)
Well I currently have about 8 pages written of notes, thoughts on head to head Burson Play vs my custom ES9038Pro DAC. In the end it ended up being very close, which is why I was volume matching. One time I forgot to match the power amp back down and we got a […]
Ran Down (1st) ES9038PRO DAC main cause of the NLOCK (~ 4 months of troubleshooting showed me, it was not the dedicated TCXO clock module):
This single loose solder ball (could have fallen inside the enclosure at any point) might explain all the problems I had with getting the DAC to lock on to any audio signal. It would be a great job if it wraps up the issues. Stay tuned to find out if I was right! […]
