    iFi Audio Micro iTube2 Buffer

    I very much like the weaker of the two 3D+ settings, with my near-field monitor setup, but the stronger setting sounds to me as if some unappealing reverb was added. A majority consensus should rule, here, so again, I would encourage you to survey your customer base. I appreciate your...

    iFi Audio Micro iTube2 Buffer

    Hi! Thanks for asking! Five changes come to mind, a couple already mentioned: 1) Add an actual Bypass switch, that works whether the iTube3 is powered on or off. (Others have requested this feature.) 2) You might want to poll other customers, but I would prefer a choice of 3bB and 6dB...

    iFi Audio Micro iTube2 Buffer

    I recall reading that, indeed, but it's kind of like saying, "You're not supposed to have white wine with beef." Given how nearly every album is mastered uniquely and the variables of gear and taste, there are no rules to follow here. It's almost entirely subjective. I have to agree, however...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    Yes, there are at least three schools of thoughts, here: 1) Use nothing but grounded-neutral secondary ITs (ideally, just one big one with all component power cords plugged into outlets that are as close together as possible, sourced from that one ITs secondary). 2) Use nothing but...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    It's importamt that you understand the context for which the narrator of that video is concerned. He works at a test bench, often with energized circuits in an exposed chasis where there is a high probability of unintentenionaly electrocuting himself by simultaneouesly touching both hot and...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    That's good advice. Really, you could bring the fuse rating down to nominatlly exceed your peak current demands - even if that's well below the transformer's rating.

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    This is what I used when I "restored" the Topaz seen in the first post of this thread: Fuse Holder: https://www.amazon.com/gp/product/B00EUF6JDS 20A 250V Fuses: https://www.amazon.com/Divine-Lighting-Slow-Blow-Ceramic-MDA20A/dp/B004I36FJA Or if you prefer: 15A 250V Fuses...

    OPPO PM-2 Is Available - Post Your Impressions Here

    ^^ Not to mention... The source, DAC, amp and cables you are using, your ears, your personal taste, etc. But, I dare say, the PM-1/PM-2 are among the most consistent of headphones when moving them from one system to another - they are the antithesis of something like the HD800, which is...

    You would have to listen to know for sure, but I don't recommend using a UPS.

    Any old fart head-fi'ers still around?

    Tyll! Wow, here you are! I'm not even going to try to express my immense gratitude, beyond this sentence; you've served so many people, so well. Best wishes!

    The Opamp thread

    I paid $75 each for two Muses02, from Mouser, at a time when they were difficult to find (Feb. 2014). About four months later, I tried to trade them here on Head-fi suggesting an even swap for Muses01. I kept that classified up for another four months and then killed it. I still haven't...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    I'm really surprised to hear this. I thought all of the Topaz and alternate brands of these transformers were manufactured with grounded-neutral secondaries. Maybe some of them have been modified over the years by previous owners, but it's possible some were actually manufactured that way...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    Hey oneguy! That's literally what defines these Topaz isolation transformers as having "grounded-neutral secondaries" as opposed to transformers like the B&K Precision, that have "floating-neutral secondaries. Both types provide common-mode noise rejection, with attenuation in the higher...
