Today I set up my new MicroRendu, however I’ve been playing with it for a few hours but I still cannot find the best setting. Basically I want the best signal path (Lossless the purple star) with DSD enable and be able to control the Volume from Roon (because my amp does not have a remote).
These are the steps that I’ve done and not succeed:
In MicroRendu web setting, change Volume to “Hardware” or “Software”, select Native DSD --> DSD up to 256 is enabled, I can control the volume but the sound is distorted really bad. Changing Zone Setting - Volume Leveling to Auto can fixed the distortion but only “blue star” (see screen shot 1)
In MicroRendu web setting, change Volume to “Hardware” or “Software”, select DoP → DSD up to 128 only, also the sound is distorted. Again changing Volume Leveling to Auto can fixed the distortion but only “blue star” (screenshot 2, 3)
If you really want a “bitperfect” rather than an “enhanced” signal path, turn off all DSP In Roon and use the hardware volume control on the Brooklyn (or disable volume control on the Brooklyn and control volume via a pre-amp).
I’m not sure what this buys you, but you can’t have “bitperfect” and DSP (including volume leveling and software-based volume control) at the same time. (“Bitperfect” is so 2010. )
Not nessarily better, but not necessarily worse, either. My point is that if you want volume leveling and software volume control, and it sounds fine to you, then use it.
(However, you might want to do some comparisons with digital and analog volume control on the Brooklyn, as well as with volume control via a good-quality pre-amp to see if you can hear differences. From what I’ve read, Michal Jurewicz thinks the digital volume control on the Brooklyn is pretty good.)
Are you using the volume control on the Brooklyn, also I seem to remember this had 2 line out sensitivities. One higher at studio levels and one with a 6db reduction for consumer kit. Have you checked that setting? Maybe you are overloading the input on the amp.
I think you need to use the jumpers on the brooklyn. They are designed to reduce the output of the DAC (as it is higher than consumer DACs) for people who are experiencing distortion in their amp. See section 8 in the manual.
As your amp is valve, i would have though the hotter input would drive that a bit too much (like an overdriving guitar amp).
