    iFi Audio Micro iTube2 Buffer

    Very late to this party, I am thrilled with the iTube2. Thanks ifi - and thanks to all the contributors here! This thing is a "Swiss Knife" for modifying your sound, with multiple features at the ready. I rode the controls obcessively, early on, but now, I know exactly what I want as soon as...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    Thanks Chris, As evidenced by many great posts, there are several contributors here who have a much better understanding than I do on how to make the most of these low-capacitance ITs. The good news for the common audiophile is that you can accomplish a lot, just by inserting an appropriately...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    I really don't want to start reporting measurements for anything else, especially since field strength varies greatly with brand, not to mention proximity, but several appliances/devices in our home are far "hotter" at 18 inches than the Topaz transformer and APC regulator (I.e. Cordless...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    Here are some EMF measurements, but the opinions as to what levels create a health hazard are as varied as our tastes in music, so I will leave that to each reader to research on his own. I will offer my opinion that this 500vA Topaz and the APC voltage regulator are "safe" even at 18 inches...

    It has been several months since this price was last available, but it's currently at $98, again. :-) This did wonders for my PC audio setup, by the way. I really can't overstate just how pleased I am with the SACS9 subwoofer. Sure, you can spend a lot more for tighter, faster, more powerful...

    Any old fart head-fi'ers still around?

    Hey Skylab, Your series of portable amp reviews was the driving force behind my getting carried away with headphones, when I joined in 2007. I really appreciate all the hard work you put into those reviews, especially since I always found them to be trustworthy, including your review of the...

    The Opamp thread

    Responding to some questions asked above... I've only tried the 2x Mouser Muses02 in the input stage of an iBasso PB2 amp. I have no doubts about how they sound to my ears with my gear. They suck! :-) They are anything but accurate in terms of frequency response and poorly resolving of fine...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    ^ No, it's not grounded at the receptacle, but under the coils somewhere. At the receptacle, I've proven with my multimeter that Neutral and Ground are connected.

    Oppo HA-1 Impressions Thread

    Wow, that was quick - thanks, both of you! So, the common thread here is that neither of you are using the HA-1's USB receiver. I found that using even an inexpensive USB-to-SPDIF converter with Coaxial out to feed the HA-1's DAC section was superior to using the HA-1's USB receiver - at...

    That's impressive. Which input(s) are you using for the HA-1 DAC? Again, this is nice to hear, but which inputs are you using? Thanks guys!

    Oppo Sonica DAC (an affordable ES9038PRO Sabre DAC)

    I don't have the HD 800S, but I do have the HD 800, as well as the HA-1 and the Sonica DAC. It really depends on which input you are using, as the HD 800 sounds a lot better with the HA-1 when not using the HA-1's internal USB interface. Optical or Coaxial inputs sound smoother - a little...

    Oppo HA-1 Impressions Thread

    I would say the HA-1 is much better suited to the LCD-3 than the HD 800 or HD 800S. The Senn HD 800 and HD 800S are about the only headphones that aren't a good match with it, but they are finicky with a lot of amps.

    Hey Alex! Thanks very much for the clarification! I couldn't remember the details of John's advice regarding DC filters (nor even how to spell his first name!) LOL Like watching a movie you haven't seen in years, everything you've written came back to me as I read it. Sheesh! And for...

    ^ Good hunting! Specs for the -31 and -32 models can be found in this PDF: http://www.pacificparts.com/vends/mge/images/t1.pdf Prices seem to be a bit high, overall, but when you search for anything on eBay, you can look for a checkbox along the left side of the screen that says "Completed...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    ^ Thanks for this valuable info, Zenvota! Let me add that using more modern approaches to common-mode noise suppression comes with some pitfalls, but I will leave it to some of the more savvy contributors to reinforce (or rebut) what I'm saying. I just can't remember the specifics, but in the...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    So far as I can tell, any mention of interwinding capacitance is conspicuously absent in the specifications for those new Eaton isolation transformers. I'd just as soon buy a $100 500VA Tripp-Lite brand new, if I was willing to forgo the benefits of a 0.0005 pF capacitance. Those new Eaton's...
