I know it's not a V281 but it's for a V281.

I received this today from Violectrics:



XLR extender (7 meters long) made at the V281 specification. Thanks to Fried.

So well built.

I will test tonight. I'm in my happy place. I can go back to using the NightHawks and V281 combo.

Moreover, they can do special purpose cables on request ^ ^ ^ :)

Interesting. I had no issues with my V281 and my Kassandra DAC and that has 10v on RCA, maybe touch less, but is hot. It sounded great, no distortion or any issues. I ran it like that with no pre or post gain or reduced gain. I had the pot at about 10 oclcok on the LCD4 for normal to loudish level.

10V on RCA from a DAC? That's so high!

For 3 yrs I ran an Audio GD NOS 19 DAC w/2.5V output on the RCAs. Going from my previous DAC (w/1.8V on RCAs) to the AGD caused gain/mismatch havoc in my rather complicated desktop system. But thanks to the V281's operational flexibility & the presence of an electronic crossover w/its own gain pots, I was able to quickly adapt to this 39% bump in system gain.

Even 24 dBu is okay in most cases (For V281! Not sure about V280).
But the measurements will show the distortion.
The signal will be affected at the highest peaks only.
And in the case of the ladder DAC such distortions are even less important.

I joined the club just emailing back an forth between Author was planning to meet and pick up the amp but didn't feel like driving. I got the v281 coming was wondering about the gain switches.

The gain switches are one of the strengths of V281. They allow you to match headphone impedance. Any headphone you have can be easily driven by V281. Even 600 ohm headphones & planars.

So I have Verite which are 300 ohms how would I choose the right gain switch? Would it just be volume control or something to do with just sounding better?

Ideally you need to be around 3 o'clock on the pot to listen really loud.
You can test and find what is to your liking.

I think there is a general consensus that using the balanced headphone output really allows V281 to shine and strut it's stuff. That said, the single ended headphone output is also very very good.

Balanced is the way to go to enjoy it in it's full glory both amp stages working together.
Single ended is like listening to a V200 exactly.
Not bad at all!

1) Always go balanced with the V281 to fully utilize all 4 amps inside.

2) Start with 0db (default) and listen for a few days, acclimate to the sound, get a feel for it, dive into it. Afterwards try -12db and see how that works out for you

So its more of a SQ thing then getting the right amount of volume like using a high low gain on other amps.
Thanks
