Looking for a headphone amplifier

[CallMeMike]

Thx guys, and Mike, yeah, you're right. But I was already aware of the extra costs.
Last year I bought some Mickey Mouse Earrings for the wifee...it was only $26 (roughly €22.6).
When the delivery guy came, I had to pay him another 20 euros for customs. He told me that, by default, anything (not electronics) over €22 gets at least an additional €20 for customs….expensive earrings. BTW, my wife already lost one… :-(

Anyway, I have 3 headphones and 1 earphone at home:
- Shure SRH1540 (46 Ohm - Over Ear) => Fantastic sound, very comfy
- Sony MDR-1A (24 Ohm - Over Ear) => Most used
- Sennheiser Wireless HDR180 (N/A  - Over Ear) => Great sound but not happy about the wireless part (it uses 2.4GHz...duh!!!)

- Shure SE425 (22 Ohm - In-ear)

Anybody an idea about that S.M.S.L. T1?

Update: about customs and stuff, I no longer buy in the US. Mostly I buy my stuff on Amazon.de and if you look at this, a lot comes out of China :-)

The valve amplifiers are an acquired taste (the coloration of the sound brought by the valves is uphold by many as the only true audiophile goal...).

Judging by your suggestion I volunteer some quick finds from UK sources:
- Project HEAD BOX DS (Black) £279
- Arcam rHead £168
- Cambridge Audio DUO  £199 (yes, it is a Phono and HP amp)
- SMSL SAP-12 Class A/B Headphone Amplifier  £120

A closer to home (and wise choice): Pro-ject Head Box S2_AmazonDE

A wider choice (again, UK-sourced list): http://www.audioaffair.co.uk/headphones/headphone-amps

I've been using for a few years mainly an Objective HP amp manufactured by a British company, Epiphany Acoustics (now 'out of business'). The amp has been designed by a chap called NwAvGuy (history here: O2 HP Amp and DETAILS ) This chap tried (and achieved) to demonstrate that spending inflated amounts of money doesn't bring neccessarily a matching hi-tech device). He made available over the Internet the product design specifics thus triggering a world-wide follow-up (one of the 'names' being JD Labs amongst others). If you can find a used Objective-based amp I'd say 'go for it...  

Happy hunting!
