Amplifier for akg k340 (400ohms)

[Oskar2905]

What amp can you recommend for high impendance hedphones like akg k340? I prefer solid state designs. I prefer warm sound with lot of bass and forward mid. I prefer "rounded" treble.

High impedance itself is not a problem because the rule in solid state is "low drives high." That is, low impedance outputs feed high impedance inputs.

However, broadly speaking, high impedance headphones need more power driving them, and the AKG K30 is known as a particularly hard case. Google:

There are quite a few informative posts and articles.

Btw, here is the true impedance curve of the K340 (I've measured it with ARTA).
