HELP! I bought equipment drunk, don’t know anything.

Please do not sit down to assemble the Elekit with a bottle of your favorite wine at your side. Maybe a glass or two will be OK, but after that I predict the odds of installing a capacitor bassackwards with rise 15 percent with every additional glass. But I sympathize with your predicament. I had a small stroke in 2019 and found my impulse control lacking afterward. I distinctly remember clicking the “Buy” button for a PS Audio Directstream DAC for “just” $4,000 — roughly the combined cost of my amp and speakers — and then wondering what the hell I’d been thinking. I sounded so nice I kept it, so I hope you have the same happy ending.
