Don't feel bad, your post is as impactful frankly, and I agree after testing on less powerful, and quality inputs, susvara is not a monster to enjoy buy can be on many types of systems. Better ones are just better...
Thanks, I am using a simple JDS Labs OL DAC, feeding the Marantz PM-5005 into the HE Adapter box, into the Susvara, and I can enjoy that system for long periods of time. I am not fortunate enough to be in a high earning job (only 23 to be honest), but at least I am working in a job I like. I would never be able to afford either the Susvara or the monoblocks listed above, but can appreciate these headphones for what they are, a true work of art.
Many people drive the HE-6 off old vintage amps, the Susvara sounds better out of the Marantz PM-5005 than my other amp the PM-44 MKII SE, the PM-44 is too smooth, wheras the PM-5005 is flatter but still slightly smooth which allows for long, fatigue free listening, and plenty of power for the Susvara.
