Problem with phono stage


Hello Fellow Audiogoners,

I need help with my Phono stage. It is Lehman Audio Black Cube from Germany.  It was recommended from Simao, a very respected Audiogon member who helped me a lot when I was building my stereo. It costs 450$ brand new which I bought used from this site. Michael Fremer considers it one of the best steals in phono stages. I get a little bit better detail and bass extension BUT it also much noisier. I can hear the pops and any other noises  on the records much more then with the phono stage of my Arcam FMJ 28 which turned out to be a surprisingly good one considering it is an integrated one.
I also switched the cables but the noise is still there.
Is this a common problem with added phono stages as opposed to integrated ones or something is wrong with my phono and needs to be checked.

All help will be greatly appreciated.
Emil

If I may piggyback on the OP thread, coincidentally I was about to open a discussion on the capacitance VS shielding subject.
Ralph is totally correct on the capacitance subject which is something I discovered on my rig with shielded cables, hum and other artifacts are present. On the other hand Chakster has a valid argument, with unshielded cables my TT makes pops on the right channel with no vinyl playing and a radio station gets induced on the left channel, funnily enough only with a Stanton DJ MM cart coupled, with the DL-301 mk2 MC don't get the radio station or the pops go figure, this is with no vinyl playing.
So where do we compromise? Apparently some shielded cables can achieve low capacitance too but these are rare.
Any of you with experience in this subject.
Trying to make sense of Bob Dylan at the moment, never been a big fan, good night guys.



Speaking of capacitance, phono cable single ended and balanced, will capacitance of the cable affect the same on either case?
Well this escalated quickly, from the last few posts I think of use for the OP Mijostyn summarized

Phono stage overload, loading and lower capacitance cables have been mentioned. Does anyone have other ideas for emilm to try?


I would add if the cable in addition to low capacitance can have some shielding (always low capacitance listed by the manufacture of the cable with the shielding included) if you go DIY shielding results could be unpredictable.
