Will an Isolation Transformer Help My Digital?
Which Chord? I had a similar issue when I had the Qute EX in the system. Bought a Bricasti and with the Chord out of the system the noise disappeared. Tried every trick in the book from isolation transformers, to balanced power transformers, to active and passive ac conditioners. Nothing worked until the Bricasti showed up and now it interfaces with my Audio Magic cond very well. YMMV |
Whart, you ask a great question which I'm not qualified to answer. I'd love to own the Equi=Tech 10 KVA :-)! I still own an Equi=Tech Q2. Check out http://www.corepowertechnologies.com You could always send an email to Mark at that site or ask that question on the CPT discussion forum here on Audiogon, or phone him. When he sees your question he will answer. It's my understanding that somehow it's balanced power, but that's the limit of my knowledge. LOL! |
Lak, I have a similar setup, and don't understand why it isn't among the first upgrades on the audiophile radar. My isolation transformers are Plitron. Lowrider, before you spend big bucks, you might want to consider a nice used power supply for the cost of a mid-market power cord. I have bought many a good used piece from Sphere Research in Canada, and never a dud. I would call them and explain the issue, and go with their recommendation. HP power supplies from their glory days, for (Canadian!) pennies on the dollar. |
Another thought, Lowrider - the obvious place for a manufacturer to skimp is on the power supply. But high fidelity begins with pure power, because every bit of garbage, grunge, or harmonic which is generated by a power supply is going to end up amplified in your speakers. You might find that with a lab grade power supply, your equipment sounds better than much pricier stuff with manufacturer's compromises built in. The old lab grade stuff cost many thousands when new, and was used to put men on the moon. I start with heroically (i.e. insanely) overbuilt power supplies for all my home-brew electronics, and it pays off. |
I have been following the CPT thread and find it a most interesting and affordable way to provide balanced power to a system. But wouldn't all the components involved need to use the CPT PC's, in my case the amp, preamp, transport/DAC. Balanced power would prevent any ground-loop and interference. @lak Your audio rig looks wonderful and I have checked out your DIY electrical work and your transformer installations. Am I correct as stated above that all my components would need to use the CPT PCs? @whart I have been looking at linear PSU's, such as Teddy Pardo, but a non-audiophile PSU with a large toroidal transformer is worth a look. Same idea as terry9. |
