Sigh. Audio Nervosa has infected me again. I truly adore my SGC as a headphone amp with DAC. It delivers great sound paired with my Focal Clear MGs. However, I am wondering if other SGC owners have gotten the itch and moved up to something that they feel is a worthwhile upgrade. I’m not looking to spend huge money, nor move away from the preamp/headamp scenario (in other words, I have no need for a power amp to drive speakers). I am currently using a separate upgraded DAC, so that’s not necessarily an essential component.
