I'm running Audio Technica MX40's on my Sabaj amp with no issues as a reference for you. This is a very good amp but you may loose range using this with K712's. If your just after a volume boost and a bit of old school valve sound for cheap this amp is excellent for the price. **Q: What is the input on the front right, the downwards arrow inside a circle?** A: It is a 3.5mm stereo jack input, although I preferred to use the phono connectors on the back of the unit. **Q: Is it only for headphone?** A: Hello, yes this preamp is designed to be used with headphones. If you are after a similar priced preamp for speakers there is a good one by FX Audio for £40. **Q: Hi! im pretty new to headphone amps and was just wondering if this headphone amp would work with my audio technica lp60? thanks!** A: Had to look this up and was surprised to find that it's a turntable! Anyway, according to AT the LP60X (sic) has a switchable phono preamplifier, and if that's the case with yours the headphone amp ought to be just fine. You need a line level input, and the unboosted signal direct from a phono cartridge will be far too weak - for that reason you should check the turntable manual before buying, but it looks like it'll be good news. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/66986163-sabaj-pha3-vacuum-tube-headphone-amplifier-2x6j9-low-ground-noise](https://www.desertcart.co.za/products/66986163-sabaj-pha3-vacuum-tube-headphone-amplifier-2x6j9-low-ground-noise) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-15*
