Type of amp: Solid State
Power output ( into 8 Ohms ): 560mW/channel
Crossfeed? : NO
Portable?: NO
Power supply : Yes. AC type. Must be used with external power supply. Optional Flat-Cap 2 or Hi-Cap maybe used in place of NAPSC
Detachable power cord? : YES
Number of headphone jacks : 1
Jack output impedance: 8 Ohms to 2 KOhms but prefer to drive high impedance headphones per company's published specs.
Jack type: 1/4"
Inputs: 1

Possible upgrades/upgrade path:
FlatCap2 or HiCap power supply or for real crazies Super-Cap2
• install a chassis mounted DIN connector instead of a provided captive lead for a possible cable rolling
Housing material: Aluminum chassis
Size: 57 x 121 x 187 mm

• Naim Headline2 vs. Gilmore V2 with Grado RS1

It's worth pointing out than Naim now have a cheaper PSU for the headline, the "iSupply".

US price is $165, nearly $300 cheaper than the previous cheapest option, the PSC2.

BTW, with a different adapter, the iSupply can power an iPod for improved performance. Only one item at a time, though.

cheers, Martin
