  1. Which would you recommend? Active speakers or a reciever? Which will get me a cleaner sound? I have a budget of about $250 for the rest of my set so with that considered do you have any specific active speakers or receiver speaker combo you believe I should go for? Thank you!

    I'm a fan of powered speakers. I don't listen to CDs anymore, or the radio. I just listen to vinyl in my living room. Receiver would be overkill for me, and take up space. 

     

    For good budget speakers, check Micca PB42x. They are listed on amazon for 120 now...I've seen the price drop to 100 buck 120 is still a good deal. In some respects, it's kind of a pain to have the volume button on the back. But for now, it's ok...I was on a budget too. 

  2. which isolation transformer did you end up using? did you just plug the entire system into it as a closed loop?

    I used this from Amazon : http://www.amazon.com/gp/product/B000LP4RMG?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

     

    BOSS Audio B25N Ground Loop Isolator Noise Filter

     

    I have a turntable (Uturn) with a pre-amp (Pluto) and powered speakers (MICCA PB42X). In my various tests to isolate the problem, it was when the the RCA jacks in the speakers were used. The hum had nothing to do with my components because I also tried an old Pioneer turntable with a built in pre-amp and still had the hum. A few months ago I assumed b/c of this it was a problem with the speakers so I went through a rather painful process to return the speakers and get a replacement. No difference. This filter was exactly what I needed. 

     

    I placed it between the pre-amp and the speakers and the hum was greatly reduced. I also haven't noticed any affect on the output either. My records still sound crisp. Best 7 bucks I spent. 

  3. I know isolation transformers help with this. Much like leds, dimmers won't allow the circuit to be charged constantly. The isolation xformer creates its own circuit. They're used in medical applications too to ensure that equipment isn't afflicted by shaky power circuits

    Thanks for this suggestion. That worked perfectly.

  4. I know that dimmer switches can create speaker hum. My house is full of them. I was curious if anyone has experience or knowledge about if it would make a difference if I replaced the dimmers with new dimmers. Obviously the ideal solution would be to get rid of all dimmers, but it's not possible (wife *ahem*). The dimmers are pretty old. I haven't seen any articles online about if there are "good" dimmers and "bad" dimmers.
