Of Meier's current line, their Symphony (which is $1310.00) has two inputs (switchable from the front), and a host of other features (most notably a DAC with coax, optical and USB inputs). Great amp-like the old Max, it's a classic. It isn't made anymore, so you'd have to find one used. I have an old Meier Audio PreHead (first generation) with several inputs (switch on the front). Their Micro starts at $333.00 and has two line inputs (via stereo mini jacks) on the back, switchable from the front. I have an older generation HeadRoom Max with two inputs (switch on the back), and still love that amp. Under the Recording Device, you will have two other options: Tie up the same type of input jacks, i.e. Trickywombat mentioned the HeadRoom offerings, some of which have multiple inputs. Mute the rear output device, when a front headphone is plugged in Make front and rear output devices playback two different audio streams simultaneously Check only the 'Mute the rear output device' option. (The tube swapping to try out different flavors is fun, too.) If ~$800.00 is your range, the Raptor is above that, however. I've had the Raptor for years, and, to my ears, it's good with most low-impedance headphones, but excellent with high-impedance headphones like your Sennheiser HD650 and a good set of tubes. My Ray Samuels Audio Raptor (an OTL tube amp) has two sets of inputs, with a switch on the back. I haven't played with it yet, as it literally just arrived. I just received a TTVJ FET-A to play with for a while, and it has two inputs with a switch in the front.
