I’ve been chasing a workplace desktop setup over the years. I’ve burned through the Chord Mojo/Poly combo & Aune B1s (sold). My latest set up is powered by a dimunitively sized Vorzuge Pure II + analogue amp.
I utilize MPOW aptx HD adapters for BT signal transmission & reception. The amp input, from my iPhone (XS Max), is driven by an adapter in Rx mode (receiver). The output BT signal, from the amp, is then transmitted (Tx mode) to my Sennheiser HD1 headphones (paired).
I’ve conducted my own casual level A/B testing...& I honestly can’t hear a sonic difference between using cables or this wireless set up. It’s astonishing how far wireless technology has grown. Transportable hifi...for audiophiles on the go...amazing!
