Will an Isolation Transformer Help My Digital?
Have not reviewed all posts however my experience with Tripplite Isobar Ultra 8 is that it is not suitable for hi-end use due to power constriction and noise. Dampens dynamics. I use three to isolate other digital, non hi-fi items, from the mains power and provide surge protection. I have been extremely pleased my Equitech 2Q and Sound Application units. |
@ptss, since there's no budget to change my power conditioning or convert to balanced power, have you ever used an isolation xfmr on upstream components? @lak, Thanks for setting me straight. So you are benefiting by using a CPT PC into a power strip. In my situation, if only the digital was in the CPT/power strip chain, IYO, would that isolate these devices? IOW, no noise bleeding back into the mains? My preamp would need to be on a separate line. (And the Tripp-lite Isobar was a major disappointment. Not at all as advertised). |
@ptss, thanks! What size would you recommend for use with an ARC CD and a small DAC? I have seen xfmr's rated in watts; shouldn't they be rated in amps? Also, is this Topaz good enough for high-end audio? http://www.ebay.com/itm/191842008876?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT |
Lowrider57, Just remember that if your isolation transformer is going to be located in your listening room, it will generate some heat and some noise (hum). For example, my isolation transformer does run warm to the touch (96 degrees F and produce 55 dB of sound with the reading taken within one inch of the transformers). The noise and generated heat doesn't bother me because the power filtration system is located in a different room. Depending on the size of the isolation transformer, the heat and noise level will vary, however you never know what’s going to happen (noise, heat and filtration wise) until you try it. |
