“Your DAC might be the first area for improvement.
No doubt the DC-1000 is a step above the DC-37. That said, I don’t see the DC-37 as a bottleneck in @fire_water’s system (atleast not yet). I’m not opposed to upgrading, but my philosophy has always been to look at the system as a whole. Before chasing a new component, I ask: have I done everything possible to optimize the performance of each piece in the chain—signal path, isolation, and acoustics included? Once those fundamentals are dialed in, then a component upgrade truly elevates the system rather than just shifting its character.
I’ve seen it too often, we audiophiles get caught up in the allure of “better gear” without realizing that a carefully optimized system can unlock more from existing components than we expect. A DC-37, properly supported in terms of isolation and partnered with a well-treated room, can easily punch above its weight. By approaching upgrades holistically, you ensure that a future move to something like the DC-1000 isn’t just compensating for overlooked fundamentals but actually adds meaningful refinement to an already optimized chain.
If you look at my system, every component has been carefully optimized to extract the finest nuances from each note. As good as the stock feet on Accuphase components are, they’re still receptive to floor-borne vibrations and energy circulating in the room. When I introduced Combak’s TU-333EX Tuning Insulators, the improvement was immediate—lower noise floor, greater detail retrieval, more convincing vocals, richer instrumental overtones, a more dimensional soundstage, and an overall stronger sense of presence.
That’s why I believe @fire_water current setup still holds a lot of untapped potential. Before suggesting an upgrade or replacement, it’s worth exploring how much performance can be unlocked by optimizing resonance control, isolation, and the signal path. In many cases, these refinements transform the system in ways that component swapping alone can’t achieve.
Just my two cents!
