In Reply to: Have choose my amp for the time being. posted by Feanor on August 3, 2019 at 05:47:19:
The Sennheiser HD 650 headphones are 300 ohm impedance headphones and they like an amp that can work well into that load. Most small, inexpensive amps do not work well with 300 ohm headphones.
A better choice would have been Schiit Valhalla or Bottle Head Crack.
If you notice, both are OTL tubed based amps. These are the type of amps that work best with 300 ohm headphones. There are SS amps that work well too but not usually the cheap ones.
If you notice your new headphones sound thin and lacking in the bass, you are experiencing a problem with the amp not being compatible with the 300 ohm headphones. The Schiit Valhalla is a good choice for those who don't want to mess with kits. The Valhalla is made in the USA and comes fully assembled and with a warranty.
The Bottle Head Crack has a good reputation with the Sennheiser but the Schiit audio product was not available when the Bottlehead amp was introduced.
I believe you will find that both amps are very good but IMO the edge goes to the Valhalla. You get much more for your money and you don't have to assemble a kit.
