iMP - Mini-Tube Amplifier for your iPod Sized Players

If mini-hifi systems don't cut it for you, Z.VEX iMP AMP is a something you might want to consider. It is a "palm sized" tube amp capable of powering "bookshelf-sized" speakers in your "office-sized" room and, according to marketing remarks, is a good couple for your iPod and alikes. As in late 90s with e prefix for .coms, 'i' is a must for all audio products that meet a certain (mini) size. And I can understand them regardless of the quality of MP3 and the player. They just want to sell the product and iPod is the best trail to follow unless you are an audiophile.


On the technical side, this little thing has following specs which are pretty impressive:

• Frequency response: 15Hz to 20kHz +0.5/-2.0 dB at 8 ohms, measured at 70 mW. No, it's not a misprint. The iMP is DC-coupled (no capacitors!) for radical sub-frequency response.
• -3dB points: -3dB@10Hz. -3dB@22kHz.
• Output Power: 1 watt/channel at 12 ohms. .750 watts/channel at 8 ohms. About 80mW at 5V rms driving 300 ohm headphones (such as the famous Sennheiser MD600.)
• Input: -20dB consumer to +4dB pro level via adjustable trimmers on bottom. Use +4dB (trimmers set counter-clockwise) for lower-impedance headphones for best noise specs.
• Noise: Better than 80 dB S/N at 1kHz.
• Residual Hum: Less than 0.2mVAC at 60Hz plus harmonics.

This little gem will set you back $525.00 that includes shipping and might say is a bargain. You can order one directly from ZVEX's web site.
