Class D
The primary advantages of GaNFETs (compared to mosfets) are low on resistance and low input capacitance.  The low on resistance allows for higher efficiency, particularly into lower impedance loads. In car audio, available power is pretty limited ... 
Differential Balanced Sound Quality
@atmasphere - Ralph - another excellent explanation. Thanks. I've been a big fan of balanced circuitry and cables since I discovered what a difference they could make in my system in the late 80s. Never looked back. 
Bulk power cables suggestions
I've also had good luck with building cables with DH Labs bulk cable - both Power Plus and Red Wave. You can get 10% off just by signing up to their email list, but they often have sales for 25% or more off their bulk cable if you are patient. I'v... 
Innuos: A Cautionary Tale.
@antigrunge2 - How did you connect the Roon Nucleus to your DAC when you compared it to the Innuous? Which Roon Nucleus were you using? Which Innuous were you comparing it to?I'm using Roon ROCK on a fanless NUC with LPS and the way I have it set ... 
Streamer or DDC
I was using a Roon ROCK connected to my Terminator DAC through a Bryston BDP2 streamer via AES3.I bought a Denafrips Gaia DDC and connected my Roon server to the Gaia via USB and then used i2s to connect the Gaia to my DAC. This was a significant ... 
Class D
It's often the case that extra filters are added to allow the device to pass FCC requirements and/or to improve stability into arbitrary loads.If you are making modifications for your own use, you can get away with it, but if you are trying to mak... 
Benefit of a Newer (Used) DAC - "Bang for the Buck?"
There are a lot of excellent DACs below $1K (new and used). In addition to the ones mentioned, I'd look at the Denafrips Aries II (new for about $800) and the Schiit Gungnir MB (used for about $950). 
Class D
@georgehifi - I usually try hard not to get personal on these forums, but you’re continued spewing of misinformation is getting on my nerves. A lot of people on this forum count on knowledgeable people to explain how things work. But you just spou... 
Class D
@georgehifi - How is that any different from digital audio, where DACs get by (very well I might add) with switching frequencies well below a Mhz? And in DACs, there isn’t a practical way to do global feedback since the input is digital, so it’s m... 
Class D
Class D is a pulse-width modulation technology, meaning that the audio signal amplitude information is all contained in the width of the pulses (which is analog, by the way). The switching frequency is therefore exactly the same issue as it is wit... 
Anybody out there replace their volume control with a Goldpoint using Vishay resistors?
No experience with Gold Point, but I build a preamp using a Khozmo attenuator which uses the Vishay naked foil resistors as the series resistor (in a shunt attenuator) and for all other signal path resistors. The shunt resistors are Takman REY. Si... 
Pass XP30 preamp makes no difference (from dagogo) ? Wow! (active vs passive vs no preamp)
The Terminator has a fairly high output impedance (I also have one). I would not recommend using a passive preamp since you'd have to use one with a fairly high impedance to avoid putting to much load on the DACs outputs. Then you're be driving yo... 
Spectral preamp picking up a radio station
The frequency band used for AM is not that high (550Khz to 1720Khz). The Spectral preamps of that age were designed with ultra-wide bandwidth, but I assume had some form of RFI filter on them to prevent this kind of interference. It's possible tha... 
High end Class D amps?
I wish it was a simple as determining a single test parameter like SINAD to determine what's going to sound good and what's going to sound mediocre. But then this hobby would be rather boring.  
Coax Digital Out -> XLR Digital Input cable?
Got it. Hope you can get it to work the way you want. If you are interested, for a bit more money you could consider a Denafrips Gaia. This is a digital to digital converter and will accept SPDIF in and has AES outputs. It has optically isolated i...
