I was dealing with hum issues as well before i sold my V200.

I'm also interested in iha-6 mk2 with lower single ended output impedance and Ha-1a mk3 with lower noise floor and a more user friendy tube rolling design.

Check out their new flagship Ha-300 thread.

Whatever you do, you will hear that annoying hum. That is the problem with Cayin tube amplifiers.

Planars don't care about output impedance.

Is this also true for iCan Pro? In Tube+ mode is negative feedback almost zero?

@iFi audio I will appreciate your reply.

Thanks for your detailed answer. What is the output impedance from unbalanced outputs?

With Nfb-1 i was hearing background noise with low impadance headphones at 50% volume. I'm not sure if it was unbalanced inputs or amp itself causing the problem. Since C2 has unbalanced design from input to output i was wondering if anyone had background noise problems with their C2s.

+ lower output impedance for single ended output.

Is there any difference between 6.3mm se outs? Manual says to use right jack for unbalanced connection and i wonder why.

If single ended output had a lower output impedance then iha-6 would be ultimate solution for most people.

I never had a good experience with Shenzen Audio. You will get a buch of apologies due to lost/wrong/damaged items.

No. It will hum badly.

Since iFi announced its 2nd black label product i am wondering if we will see a Pro iCan Black Label.

Hello @Andykong. As i said earlier it would be nice to have a chart/list of compatible tubes. Since 12dt5 tubes are hard to find Is there any alternative as replacement? Also i'm wondering if i can use 12bh7 as replacement of 12au7?

Does anyone know if Milo is using negative feedback?

Thanks Andy. It would be nice to have a chart/list of compatible tubes.

Has anyone tried Ecc802 as replacement of 12au7 and El844 as replacement of El84?

Looks great. What is the volume knob position with GEC 6as7g and HD800?

Great amp

When i connect my Bimby which has 2V output volume is around 2-3 oclock with HD800. Last night i tried with my mojo in line level mode (3V) and volume was around 10 oclock. Are these volume knob positions with HD800 or different cans?

Hello everyone. What is your volume knob position when listening to HD800? Mine is around 2-3 o'clock and i'm wondering if rolling tubes change the gain.

What is the volume knob position with HD800? Mine are around 2 o'clock. I'm also wondering which tubes affect the gain more?

  I have had a bad experience with them recently.
