Little Dot mkI + strange sounds...help

post #1 of 1
Thread Starter 

Hi All,

 

I seem to be having a few problems with my new toy the little dot mk I+.

 

Problem is i'm getting some nasty interference plugging them into my Razer Barracuda sound card via headphone out (there's no dedicated line out).

 

 

The razer barracuda plugs into my Sony STRDA1200ES AV amp via spdif. I also have a Marantz CD52 mk II.

 

I intend to use the headphone amp directly with the Marantz but would really like to use it with my PC also pref without the buzz.

 

At the moment I've got my headphone amp plugged into my headphone out jack of the Sony. Seems like a complete waste of time but at the very least it doesnt sound like ive got my head in a hornets nest.

 

Any help/guidance appreciated.

 

My Kit:

 

Little Dot mk I +

Tubes:Mullard EF95, Tung Sol 6AK5 (from the 1940s), General Electric 6AK5 (From the 1940s-50s)

OP AMP:OPA627BM's. (Not plugged in yet waiting for these puppys to arrive)

 

Headphones: Grado SR80 and Shure SRH 840 headphones.

 

AV AMP: Sony STRDA1200ES

 

CD Player: Marantz CD52 mk II

 

Speakers: Keff Eggs

 

Sound card: Razer Barracuda AC-1
