GS1000?
At first it was not the best combination, but in the end they matched wonderfully. The forwardness of this amp is perfect for the midrange of the GS1000. Bass is full but controlled. Highs are clear and detailed, but never harsh.
HD650?
Is it as good as the Earmax Pro with the HD650? Yes. Not better though, but everything as good. Senns can rock like you wouldn\'t believe.....
I haven\'t used my balanced HD650 and my RPX-100 in quite a while any more.
If you like your music full bodied, and with lots of impact in every sense of the word: this is the perfect amp.
To get to my sound impressions I had to do some preliminary burn-in.
A LOT it turned out.
At first I was not over enthousiastic: too massive, boomy bass, a bit grainy, very forward, but I decided to give it some time.
Am I glad I did.
After 100 hours it was already a different amp: much better detail, better controled bass. Still very massive and forward though.
I was happy. Good amp.
Then I did some more burn-in and it got better and better.....
Differences were not night-and-day, but considerable:
More detail, especially in the midrange.
Much better control and detail in the bass.
More extension in the highs.
More clarity overall.
Main characteristics:
Forward: it packs a massive punch.
Powerfull: sound is full bodied and massive.
After about 500 hours it stopped changing, at least I didn\'t detect any change any more.
I mainly compared it with Corda Prehead and X-CAN v8 and used my computer as source (JOB 48 NOS DAC) and a couple of thousand different albums of all genres.
I also compared it with the Earmax Pro, but only for use with the HD650.
