Distortion with ARC Ref 150 and Maggie 3.7
Yes Kevin, nothing matched the CAT preamp better than their power amp. I also agree with the 5SE/150 matching. For me, the CAT combo looks like a better choice. If I choose the ARC, I will have to buy a phono preamp as the 5SE don't have phono sta...

Thanks Al for the detail explanation. Now I pretty much understand the fundamental of both signal type.Can't wait to try the transformer with my CAT. Unfortunately I still did not received answer from either ARC, Jensen or SMc. Anyway my plan is t...

ZD, your suggestion has save me from selling an excellent amp. Today I loan a XLR cable form the Maggie dealer to try a direct connection from the Wadia which have balanced output and volume control to drive the Ref 150. Guess what? Not only the d...

Bifwynne,FYI after some serious listening, I do aware that the distortion were clearly less obvious bypassing the Zeros and used the 4 Ohm tap from the Ref 150 to drive the Maggie. Now the issue has narrowed down to the balanced and unbalanced int...

Martykl, many thanks for your input. It sure help to further justified the issue with ARC amps. But you didn't mentioned how you finally addressed the issue. Did you changed to a balanced preamp or use a transformer?Regards

Jtimothya, I didn't use adapter. It's a specially build RCA to XLR interconnect soldered according to many cable manufacturer's standard for RCA to XLR connection. I've two different set/brand of such cable but posses the same problem.

Thanks Al for the insight of single ended and balanced design. I'm sure learn a lot from you. What you've mentioned about substituted amp I used was correct. It was a pair of VTL MB125 which rated 55-watts and 100-watts into 5Ω in triode and tetro...

After many painful and time consuming experiments,I have to believe that single ended and balanced components does have mating problem. It seems like many balanced only component were designed to match with other similar or same manufacturer compo...

BTW, I do agree that my system sounds more linear and faithful to the source by connecting the 4 ohms tap directly to the Maggie. Thinking about the beginning when I first bought the Ref 150, it was used to drive my previous KEF 201/2 speakers and...

Thanks for valuable input from all! Yes, trouble shooting procedures which I've been carried out also includes bypassing the SUT and CAT SL1 in the system, by using a EAR 834P phono preamp that comes with volume control and MM/MC function connecte...

Answer to Alan:"Try increasing the tracking force to the maximum recommended for your cartridge."Another good suggestion. Will try out.

Answer to Skinzy:"I once had a similar problem and it was cart alignment issue as several others have suggested."Although I have done this many time but I will surely do it all over again as suggested by Wlutke.

Answer to Wlutke: You have described the distortion problem I have been working on for some time now, although yours sounds more severe. Mine was with high pitched, high amplitude vocal "air", mostly female, but piano was ok. I have the DV XX2 MK2...

Answer to Zd542:"Try that first. Use any CD/DVD player you can find. It doesn't have to be expensive. If that doesn't work, I would try a different pair of IC's between your amp and preamp. I don't think you can switch your amp to run in SE or Bal...
