Current sensing phono stages w/Rega?


Hey folks,

Anyone using Channel D Lino C 2.0 or the Sutherland Little Loco with a Rega RP8? 

I got some great advice here on researching my first cartridge and phono stage upgrade.

Cartridge was upgraded from the Exact MM to the Ania Pro MC on my Rega RP8.

After researching the suggested phono stages, I home demoed a Musical Surroundings Nova III (with both stock walwart and optional LPS), Rega ARIA MK3 MM/MC, Black Ice Audio F159, and a Konus Audio Vinyle 1000MC Mark II.

The Konus is the only current sensing unit and the one I like the best. 

Two other current sensing units I would like to try are the Channel D Lino C 2.0 and the Sutherland Little Loco but came across the following:

The Absolute Sound Channel D Lino C 2.0 review excerpt:

Briefly, any phono cable/tonearm combination where twisted-pair-conductor cables are employed and the two conductors are not connected to the turntable (or shield) ground can be used. An example of a tonearm/cable that can’t be used would be a standard Rega ’arm where the shield is connected to one of the outer shells of the RCA, which is also a signal connection.

Stereophile Sutherland Little Loco review excerpt:

Your tonearm wiring must be fully balanced between cartridge and phono preamp, with no connections between any of the tonearm leads and ground. That means that the Little Loco won't work, for example, with your Rega arm, unless it's rewired. 

Has anyone rewired a Rega to work with either?

Thanks everyone!

Thanks guys..I have another Phono stage coming tomorrow. Tron Convergence, which is not a current sensing. Gonna shoot em out and obviously listen for any noise from the Tron. Will report back. 

Not writing off the Konus 1000 yet, it's a really good PS. Like REALLY good.

Where did you get the information that Rega will make a balanced arm? Their US distributor is stating they have NEVER done that for anyone.

Local dealer here in New Zealand - I saw the arm when it came back.

Distributors and dealers often say things that are not true because they cant be bothered to do anything outside the norm.

I suggest you contact Britaudio in the US - they do re-wires on Rega arms and may be able to help you.

 

Got the other phono stage, it does NOT have the Buzzing noise, and as I mentioned it is not a current sensing phono, rather a voltage regulating. It’s a great phono stage, but the Konus is better, and the difference is not small. Dynamics are better, sound stage deeper, dynamics and leading edges better, bass it tigher and stronger. Its like the gain is turned up more than it is on the Tron, neither have adjustable gain.

Creates a dilemma since the one that sounds better has the noise. I am going to call britaudio next week to see if they have seen this before and see if they can validate that if I rewire the Tone Arm it will solve this issue.

This morning I reviewed this thread for some reason. To sum it up, the OP reports that his Rega TT works fine with the Konus phono stage. He posted here because he is contemplating the purchase of either the Channel D Lino C or the Sutherland Little Loco phono stage, and he is aware that the Rega TTs cannot do balanced connection to a phono stage. Both the Lino C and the LL are balanced, for sure. But the point is that the OP is currently using the Konus and a Rega TT with no issues. I then looked for specs on the Konus. So far as i can tell it is single-ended, much to my surprise. However, neither the description on the Konus website nor any of the reviews is really very good at describing the technology. Photos of the rear of the Konus show only RCA inputs and outputs, further leading me to believe it is SE by nature. This explains why Hleeid has no issues. He WILL have an issue if he elects to purchase a Lino C or the original LL. (I gather the LL2 is now capable of accepting SE inputs via RCAs.) But we know there is an easy fix.

Then along comes jc51373 who is having loud hum with his combo of Konus and Rega. I and several others heretofore assumed this was due to the incompatibility of the Rega TT with balanced operation, owing to the way the Rega is grounded. (I confess that due to my thick skull and careless reading, I hadn't previously noticed that the OP has no problem with his Rega/Konus set up.) And we suggested there is a simple fix for that. JC himself seems to have assumed that his hum is the fault of the Rega. But since the Konus appears to be SE, JC’s problem cannot be that simple. JC needs to look elsewhere for the cause of his hum, maybe a broken ground connection somewhere. Funnily, if the internal connection between the tonearm body and the L channel audio ground (described by Dover)  has been disrupted, that would cause loud hum in SE operation. Just saying.
