    Left channel hum...driving me crazy

    Not sure where else to post this, but my SRM-1 Mk2 Pro has developed an infernal left-channel hum/buzz (sounds like a very quiet 60hz sawtooth wave) that is dependent on position of the volume potentiometer. I Thought it was a problem with a filter cap at first (electrolytic, installed a few...

    TrueFi "calibration" mini-review

    TrueFi is a program that purports to generate a flat sound. For the most part, it does--maybe a bit too flat, in fact. It wildly boosts bass on cans with a lot of rolloff (e.g. HE400i), which seems to muddy the sound a bit. Most audiophiles don't like strong bass for this reason, but like...

    Tonal memory/slightly-imperfect pitch

    I was taking some audio-related tests, and there was one for perfect pitch. I've known for a while that I know when something is off by the slightest bit in pitch, but don't think I have perfect pitch (even after this), as I never learned the scales. I did use two reference notes, so I had a...

    Awful listening room--with a loud fridge.

    I'm stuck in a privately run dorm room...and the desk is adjacent to a full-sized fridge. I can't just throw the fridge away, as it is the proprietor's property, so I have to deal with an annoying pink noise all the bloody time. I usually don't listen to my music very loud, but i have to turn...

    Has nobody else tried these? I bought two pairs (one was massdrop, and it broke, so I bought a warrantied one on Amazon). For the money, they are basically unbeatable, especially in customizability. I run them airy and treble-heavy, with both blue filters and silicone tips. They have amazing...

    How does the Woo Wee converter+poweramp compare to SRM-252?

    I'm about to sell my whole setup to finance stax lol. I'm still not sure it's worth it. I could afford it if I just got the 3100, but I want to get the Woo Wee converter and a good power amp, for clarity and soundstage. I'm probably gonna get the Parasound Z-amp v3 as a power amp, run...

    Foobar won't output >16bit

    Hey all. I have a DAC capable of 32 bit, DSD-enabled audio, but Foobar refuses to let me do more than 16 bit, even with FLAC files I know qare 24 or 32 bit. I've also tried it with my other DAC, which is 24-bit capable, with the same results. Tries ASIO as well, hoping this would change it...

    About to buy Stax 3100 (already dying of fun bux poverty)

    I'm planning to buy Stax L300's tomorrow, after I've had 2 nights to contemplate the fact that I'll need 5-year plans and virtual slavery to fix my personal economy afterwards. I think it will be worth it. I'll be done sidegrading. Maybe. Maybe I'll just pull a Jordan Belfort to finance...

    DAC and amp advice for DT1990 or Hifiman Sundara (undecided)

    I'm considering a Sundara or DT1990, and have been informed that my current source lineup is insufficient to make them sing. I currently have a Little Dot I+ with an LT1364 or AD823 op-amp (I switch them depending on music) and Voskhod 6ZH1P-EV tubes. I drive this via the SMSL M6's onboard DAC...

    Little Dot I+ tube and op-amp rolling + recommendations given

    Testing was done on Soundmagic HE400i headphones, carefully EQ'd to be roughly linear. I used an HRT Music Streamer Soundmagic II for this test. Tubes: 6JI tubes (one of which burned out after 56 hours): Stiff, dry and congested in the centre-mids, and ran hot in the upper-mids/lower treble...

    Steampunked Little Dot

    I used some ancient rub 'n buff to steampunk/dieselpunk my Little Dot I+. I bought newer paints, and a few colors I lost, and will make a much more appealing revision soon. I feel a tube amp should look as old, different and awesome as the tubes themselves.

    FiiO customer service is awful

    Hi all. I've been through two FiiO players--the X3II, and the X5II. The X3II randomly stopped working after about a year and a half, and I used squaretrade to upgrade to the X5. I've treated my X5II well, and a week ago, I set it down, functioning, and picked it up to find that it was not...

    Brilliant linearizing/neutralizing EQ for Hifiman HE400i--like whole new headphones!!

    Hi all! I found an article in which someone has produced a linearizing set of EQ parameters (works well on equalizer APO with Peace installed) for the HE400i headphones. I believe this is for the newer version of the 400i's, as it matches with FR graphs I've seen for the new ones, and sounds...

    Desperation strikes--ghetto heatsink

    I was fiddling with the gain setting on my Little Dot I+, and it occurred to me that the op-amp was running pretty warm, perhaps warmer than typical for solid states, and that I'd seen people running metal op-amps with heatsinks. I had a plastic-shelled op-amp, which isn't conducive to heat...

    Very-low-voltage op-amp rolling (for Little Dot 1+)

    I'm figuring out optimal op-amps for my Little Dot I+. It supplies two parallel lines of 3.7v--so 3.7v--to the op-amp. There's less info on many choices rated for such a low voltage than for more typical voltage floors. It seems that running a higher-voltage op-amp--the OPA2107AP for...

    Op-amp rolling recommendation requests for Little Dot I+

    Hi all. I've heard the stock opamp in the Little Dot 1+ is a bit unrefined--loose in bass, a tad congested, and generally lacking transparency. Thus, I bought an AD823ANZ. But my question is this: I've heard a lot of good things about the 627/637, 2107, and a few others. It would be great if...

    LZ-A4 vs 1More Quad Driver

    I'm looking at the $200 range again, and it seems a new competitor, the 1More Quads, has entered the ring I'm contemplating getting a pair off amazon to audition against the new set of A4's I just got, and will return one of them, but I wanted to hear what you all thought. I used to own the...
