Soundstage gone


Hi guys,
I was really happy with the sound I had from my system until I decided to upgrade my turntable to MC stage. What I had: Linn LP12 with Lingo 3, Akito tonearm and Adikt MM cartridge. The amp is MA2275, speakers B&W 802. Recently I upgraded TT with Radical power supply, Urika MC internal phono stage, Ekos tonearm and Kandid cartridge. My amp has only MM phono stage, so tried to plug the cords from the table into other available inputs: CD2, tuner or DVD. The sound was amazing but the soundstage almost gone. I was shocked. There is no more splitting sounds between speakers and all the records plays as mono. Is there a way to fix that? Forgot to mention: I have a dedicated power line and my cables AQ Hurricane, AQ Oak.

If you have a mono button on the amp play a mono record, if when you press the mono button the sound nearly disappears you have the cartridge leads crossed on one channel, if it doesn’t its in polarity, the background noise might reduces if it’s an old mono disc but not the music.
From what I read, OP has no phono equalization. Going from cartridge into MC gain stage, then into line level. Totally bypassing the necessary RIAA equalization stage. Yea, that would sound exactly as he describes!
Wolfie62: the Linn Urika is an mc only phono stage and has the RIIA equalization. Is intended to go straight into a line input without any additional stage. It's also designed to work with the Linn Kandid cartridge but works very well with other mc cartridges.
I'm quite surprised by most of the comments above, no knowledge at all of the products...
OP, your dealer needs to visit you at home and fix the problem (this is what I will do with my customers).
Only way stereo comes out as mono is if there is a short circuit between the two channels.  Suggest carefully check the cabling from cartridge to mc stage. Include the wiring within the arm.  This is easy with a meter.   If ok try bypassing phono stage...volume will be very low but may reveal whether short is in the phono stage.

Take it other sources play stereo normally? 

You correctly chose alternate line inputs as otherwise there would be 2 riaa equalisations in series. 

Good luck. Let us know how you solved the problem.
