Hi,

So I'm kind of new to the game and when it comes to knowing what makes an amp any good or not I'm completely lost.

I recently purchased a pair of high quality headphones; Sennheiser HD 598s and I want to run them as best as possible. I've heard it's best from a full system with a real amp and either from a CD or from vinyl. But I have no idea if my amp is any good or not. The same goes for my record player, but I'll probably post a separate thread about that later.

Anyway, my amp is a Kenwood KA 893. Here are 2 link with specs for the amp and the headphones:
Kenwood KA-893 | Owners Manual, Service Manual, Schematics, Free Download | HiFi Engine
Sennheiser Canada Inc. - HD 598

So is my amp any good for running my headphones? If not, why not and what would I be looking for in an upgrade?

Also, it has a phono input, but I also own a phono preamp that my dad gave me. Should I plug my record player into the amp's own phono input or into the preamp and then into the amp?

The preamp is a bozak madisson clk-ph2, the specs:
Impedance: 50k ohms
Gain: 50X (10mV in = .6V out)
Max. Input: 35mV
Response: 20-20KHz
Max. Output: 1.9V
S/N Ratio: -60dB
Power Requirements: 117VAC, 60Hz

Thank you very much for taking the time to read this wall of text and thanks for any responses, I appreciate it.
