NOS Chips vs. Modern Discrete R2R: Are those Chinese PCM58/PCM63 DACs worth modding, or is it time to move on?
First off, apologies for my English (I'm from Italy) and to be clear: I am not a seller, just an audiophile. I previously used a Chinese DAC with a salvaged original PCM58 chip (for reference, the one in the attached photo is the exact one I owned). I immediately swapped the stock op-amps for genuine Mouser NE5534s. It sounded great for the money, delivering that thick, tube-like warmth and forward vocals I love. However, I hate a soft, rolled-off sound, which is why I use highly dynamic cables and rhodium connectors to keep transients fast and punchy. Now I feel like I’m hitting a glass ceiling because I'm craving more micro-detail and resolution. My question is: is it worth throwing more money at this basic Chinese board for high-end boutique components, or should I just pony up and upgrade to a product like the Denafrips Enyo (Ares)? I want to keep the analog warmth but gain resolution. Would love to hear from anyone who has A/B tested this.
