@Nitewulf you have recommended the complete other side of the sonic spectrum. I could take a photo right now of my rack and you would see Metrum Adagio, MSB Analog, Rockna Wavedream Sig Balanced, Vermeer 2. Jeff Rowland Aeris with ultra cap power supply, Stello D700, MBL 1511, and Denafrips Terminator. The last thing Wes wants is MSB Analog or Metrum Anything. Way too rolled off for his cymbals. No leading edge on either of them. But they are excellent DACs for people that like Euphonic sound. I am the seller that listens to everything so I can talk from personal experience as it's more valuable than anything. Plus I'm actually an Audiophile before anything else, this is passion for me, not a job or business plan. So far Rockna is my Reference. Nothing can image like it that I have heard. It has a realism that's chilling. My body actually perceives another being in close proximity during vocals. Strange and fun. So about modular. I'm not sure how it's being used here but if you simply count boards everything is modular unless it's all on one board. So Rockna is modular. Most well recognized are the R2R DAC modules. 4 of them for differential operation. Differential build is twice the parts and twice the labor. Only committed companies go through that balancing act matching parts values between sides. It's a pain taking process, most companies just put XLR sockets out
back but the circuit is single ended. Even my $22K Vermeer2 is single ended. Not Rockna with the Balanced Edition which is what Wes bought. So Rockna is behind many OEM designs. They are behind many others world class DACs. The layout of the boards and the proprietary algorithms are what separates the men from the boys. I pick my digital based on the Engineer not the mechanical features of the chassis. Nothing matters more. Gotta get back to soldering some crossover cards, I'm doing a fully active quad amp rig tonight.
