Also commonly known as a β€œstereo” 1/4 inch plug. You would use this if the amplifier you are using has a balanced input. If not, then use the RCA jack output with an RCA plug on both ends of the cable. You can also make your own cables, just make sure it’s wired correctly for the balanced outputs. Just keep in mind, rca plugs or cables are NOT balanced. **Q: How do i get my pc to display the 768khz... only seeing up 300ish khz (currently at work and forgot actual bitrate)?** A: You can go to Sound Control driver properties and select the output. I think it’s maxed at the connected DACs max or the USB max but I’m not certain of that. **Q: Which has better audio quality and performance the E50 or the E30ii** A: The E50 is superior in my opinion. ## Frequently Bought Together - Topping E50 Mini HiFi DAC ES9068AS DSD512 PCM768kHz USB DAC USB/Coax/Opt Inputs RCA/TRS Outputs Decoder for Home Theater Game Music Black - TOPPING L50 NFCA Headphone Amp SE/BAL Input 6.35mm 4 Pin XLR Output 3500mWx2 Mini HiFi Desktop Home Audio Amplifier (Black) - Monoprice 1/4-Inch TRS Male to 1/4-Inch TRS Male Cable - 1.5 Feet- Black, 16AWG, Gold Plated - Premier Series --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/382492718-topping-l50](https://www.desertcart.hk/products/382492718-topping-l50) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-11-06*
