    Aune T1 OR Objective2 for DT990 Pros...which is smarter?

    There's the deal for the Aune T1 and from what I've read, it's a nice dac/amp for these headphones so long as a get a different bulb. But really, it's not a great deal after the duties and taxes, and shipping to Canada. It will easily come to $160-$190 CAD. Up until tomorrow I can still cancel...

    When using an amp (Objective 2) connected to laptop, should you set amp's volume to max and the laptop's volume low? Or . . .

    When using an amp (Objective 2) connected to laptop, should you set amp's volume to max and the computer's volume to a low level. Or should you, say, set the amp's volume to mid and set the laptop's volume to a higher level? Does it make any difference?   Thanks. Just curious how experts do...

    DA&T AC Filter Impression

    I have thought hard before writing this review whether this is the right time for it as I am still waiting for an important piece of my set-up puzzle, the DNA Stratus. But heck, if my current less-than-perfect set-up can yield a performance that I have never experienced before, I have no doubt...

    Objective2+ODAC combo (Rear Power) vs Schiit Magni+Modi for Sennheiser HD 650.

    Title says it all. What is better and why?   O2+ODAC 2 in 1 combo is 295 including shipping.   Schiit Magni+Modi is 275 including shipping.   Other recommendations are welcome. To me though, these seem like the two best sub 300$ solutions for a Sennheiser HD 650.

    I'm a newbie when it comes to audiophile and high end equipment, but for the last couple of months I've enjoyed my new stereo system I put together to play vinyl records. My next purchase I'm looking to make is on a DAC. I recently ripped my entire CD collection to flac on my desktop. I'm not...

    Battery Powered Desktop Amplifiers ......

    I'm wondering if it would be possible to use this thread to list Desktop amplifiers, which run on battery power ?   I know Blue Audio does this, but am not sure about others.

    Objective2 Amp (Built by JDS labs & uncased) SOLD

    I bought this a little while ago, really haven't found a use for it so it needs a new home.  I think the front panel is now on sale at JDS for $10.  Glued the volume knob on so it wouldn't keep falling off, some buyers have asked how hard it would be to take off -- I don't know.  I haven't put...

    [Review] JDS Labs Objective2 Amp

        I want to thank JDS Labs for the fantastic Objective2 (O2) Amp that they've hand-built and kept to NwAvGuy specifications. John is a very nice guy who sent the O2 much faster than he had quoted and also quickly responded to my emails. I highly recommend JDS Labs if you're considering...

    O2 (Objective2) Amp with Triple Gain Switch (one-of-a-kind...)

    Nwavguy designed O2 with versatility in mind. Indeed, with the Dual Gain Switch that he implemented, it is. It provides enough juice for power-hungry orthodynamic phones with its default 6x gain, and can also operate at a lower, 2.5x gain. Indeed, if you want, you can do some DIY and lower the...

    Can I ask for a "list" of amps in the $200-$300 range?

    More specifically, I'm just looking to weigh as many options for a new amp as possible. Of course I'm not asking anyone here to list every amp in the world in that range, but hopefully a brief list with reputable/popular amps. Tube or SS is no difference to me, since I will most likely end up...
