While it is true my entire system costs only about 10 dollars, not counting tweaks, I am definitely not (rpt not) frugal. The reason I opted out of the typical audiophile system - my previous all tube Class A headphone amp and the World’s most modded Oppo 103 and Sennheiser HD-600 - was actually due to sound quality. Or at least the expectation of that possibility. That’s right. Sound quality! No more AC house power, no more AC Ground problems, no more power cords, no more interconnects, no more digital cable, no more speaker cables, no more huge transformers, no more fuses. No more pencils, no more books, no more teacher’s dirty looks. 🧐 Now, see if anyone can guess which system sounds better, my all tube Woo Audio + Modded OPPO system + Sennheiser HD-600 or my SONY WALKMAN CD Player + SONY MDR-700v headphones. Yes, I know what you’re thinking, ”Are you out of mind?”
