Interesting stuff. I wonder if it's correct about the DAC filter being benign in that scenario, though. If you have two filters in series, won't the inaccuracies of the the poorer filter still pass through the filter chain, even if the other filter is much higher fidelity?
Not sure about the new DT-990s, but the original DT-990 are not open phones. They were closed but had two small ports in the rear.   I haven't heard a single really open headphone where bass remains balanced but powerful down to 25hz, not at any price range. I doubt its possible.
+1 for GS1000. They're in their own league when it comes to low volume.

One possible advantage for firewire is that the clock master can be the DAC. For USB, it's almost always the host, and then the DAC has to deal with relocking and all of that jitter-related stuff. With firewire, if implemented well, jitter becomes a non-issue. Leeperry: galvanic isolation is cheap. It can implemented on the DAC pretty easily, and in fact it's probably better to do it that way.

At the moment, single plug 4-pin XLR. I'll reterminate to whatever though. How much voltage can the b24 put out? This thing needs 50Vpp to get loud. The impedance ranges between infinite at DC and 50 ohms at the top.
Hi guys. Great to hear there's a new meet happening. I'm keen to attend. As for equipment, I can bring a pair of Taket H2 which have just had a major structural and electrical overhaul. They can now be driven directly from a powerful speaker amp, so I'm curious to hear them driven by one of the balanced b22s I might also be able to bring a DAC of my own design, which is currently at the assembly stage. Hopefully enough of it will be finished by the date of the meet.

We all want to improve our systems, but have limited funds to do so. So then why in the world would an "audiophile" not perform such a test? I don't buy audiophile cables and such, but I can offer the following general line of reasoning, since this applies to audio generally:...
