That's the one I posted

You need 3K for 1.5x gain

Whichever pair you remove will turn to 1.0x.

Looks about the same to me (compared to VSTHost). Any comparison on delay and stability? They have a standalone version since I wrote that, but it's instable as hell. I tested 2 different versions and got tired of it. Virtual Cable + VSTHost + Sonarworks with ~50% phase correction created enough...

Yup, one of the reasons I didn't attempt a loudspeaker calibration. I live in the outskirts of my town and there is minimal traffic, but even the vents on my PC may interfere, not to mention I'd need a much better mic.

It would make just as much sense as setting up a rep at Edinburgh of the Seven Seas. The world doesn't revolve around the USA.

No, but Alex will storm in and tell you all about it XD I'm happy with the OPA1688s.

The proper statement would be I tested nearly two dozen op amps and the O2 is optimized for the op amps that proved best from what I had at hand.      Gain depends on your input. 1/3.3x is excellent for a 2.1V input (ODAC). 3.3x is actually a tiny bit more than it can safely handle. Mine's at...

I don't think NwAvGuy ever said that opamps do not matter. As far as I can recall it was more about price/performance and drawing a line where "better" opamps wouldn't result in an audible improvement.   As for the roles: the one next to the potmeter (2068 by default) amplifies voltage. The...

Mine's modded, ofc I opened it. Wires are standard copper twisted pairs, but even if they were some "cheapo" garbage there'd be 0 difference.  

Mine has a 6.3mm, a 3.5mm and 2 pairs of RCAs and no switch. Basically use whichever suits you best. I'm using the RCAs.

Yes, there is. More room for tinkering and also the ability to keep one and replace the other with something else.

Depends almost entirely on the power supply (other factors are negligible). If the DAC isn't USB powered then it should be pretty much the same. If the DAC is USB powered and is sensitive to noisy VBUS then I have no idea because I'm not an Apple person.

I didn't have any license other than the 5 day trial key I got when I tested the systemwide version. The 21 day key I got for the HP plugin expired long ago. The license worked and it did its job perfectly for a few minutes until it started to glitch out and I had to either wait, set buffer size...

They have, I got a notification on the 23rd along with a 5 day trial key. I'm not questioning its usefulness as it does a marvelous job compared to a few others I tried (by far my favorite).  

The VST works fine with Foobar (load it with its VST Wrapper). The new systemwide version is extremely unstable and therefore useless at this point. I've tested it for about a day and gave up. I don't even know how it was implemented but it doesn't seem to be an APO. You can turn the VST into a...

It activated just fine for me, but WMP refuses to play FLACs through Sonarworks Virtual Audio Device (every other output works flawlessly for WMP and FLACs). It plays MP3s and all kinds of videos tho. Foobar and MPC have no such issue and they are all set to default device.   Update: Youtube...

I only see 1 V5 (top right on the 1st and 2nd pic, on the right on the 3rd). You are probably mistaking the caps for V5s.

SS3601: single SS3602: dual   Otherwise they are identical.

The thousand dollar DACs surely cost more than 100$ (if we are talking about respectable companies). Rule of thumb for products of such quality/fidelity is usually about 600% of components. This covers research, marketing and labor with plenty of profit left. The reason for the O2 and ODAC being...

I also love the SS3602. It has clean bass and an overall very natural sound.

Prices are hardly indicators of SQ, especially in the case of TI. For example they sell top notch opamps for peanuts and vice versa. There are "high-end audio" opamps that cost 20 something $ and are mediocre at best. The K1 doesn't use the same DAC as the ODAC. The K1 has the old version while...

They will charge more anyways. An R2R is expensive by design and not necessarily better, this is why it's a dying breed. There are pros and cons for both, some swear by DS, some by R2R, but R2Rs will die out sooner or later. There's also a good thread about this in the sound science section, but...

Why not simple use DS or R2R instead. Multibit is such an outdated term as it refers to anything but 1 bit which includes all R2Rs and most DSs.
