Headphone amp combo ideas?

I really like my Beyerdynamic T1 with matching A1 headphone amp. I auditioned many headphones and amps. Another good amp is a used Musical Fidelity x-can (e.g., V3).

Headline looks cool - never heard it before. I imagine Naims pace and punch would be a good match. It's specs show it should easily drive 600 ohm T1s. Nice thing about Beyerdynamic A1 head amp is I bet they voiced te T1s with it, it has two inputs and an output.

Headline specs:
Suitable for headphones
8 Ohms to 2 KOhms

Frequency response
-3dB @ 10Hz & 72kHz

Power output (into 8 Ohms)
560mW per channel

Max output voltage
3.7V rms into 2kOhms

Voltage gain
+13.5dB

Dimensions (H x W x D):
57 x 121 x 187mm

Not to be armchair qb, but if it was me I would sell the naim PS and put it toward an A1 which can be had new for $700-800.

That's why I kept it simple and bought the matching A1 headphone amp.
