any comparisons with A90?

I’m planning to get the A90 and I’m wondering if the A90 is an upgrade, compared to my iHA-6. I haven’t found any comparison between the two.

IMO probably sidegrade at best.

Hopefully someone will compare the sound signature between the two.

my IHA-A6 had a disturbing white noise going on even on low gain low current, was horrendously worse when switched over to high gain

is this normal..??

The noise are coming from both channel or only appear in one channel? Happens on all phone outputs? only on 6.35mm single-ended? only on Balanced? Did you bought the iHA-6 recently or you had used it for a while but the noise only appear recently?

through XLR, didn't try on 1/4; brand new from 3 days ago

I think I have the same problem on mine, only on XLR, only on Left channel, first 5 minutes after switching on from cold it works fine and then white noise over the music. I need to get it repaired but the whole Covid situ had stopped me from sending it out, and then I became lazy and forgot about it.

Do keep us posted on how you tackle this.

I posted this a while ago and recently I've not got the problems back yet (maybe becuz I'm not listening as much) But I get buzzing sounds once in a while in left channel XLR out in low gain, completely black on high gain.

Can you try touching the headphone cable or the amplifier itself when the noise happen

 

[nanu]

Nothing changes when I do that, the noise is still there and no change in its characteristics.

This is a nice surprised, we are flattered by the recognition of HEDD Audio and Headphone.com

Was hoping someone could help me on an issue with a iHA-6 I just purchased. I seem to also have a hum that some others have pointed out. It only occurs with the following settings:

Input: RCA and XLR and with no cables attached on input
Current: Low
Gain: Low
Output: 4 pin XLR, 2x3pin XLR

The hum seems to be stronger out of the left channel than the right.


This does not occur when the Current is set to "high", and when the gain is switched to "high" there is a hiss that is typical of switching an amplifier to high gain, but different than this hum I'm hearing. Anyone have any help on this?

@Andykong

I've owned that amp plus the matching DAC and the matching DAP for two years now ( tri-stack ) , now issues. Are you using the amp standalone, or with a DAC .. are your cables compromised in some way?

Hard to say what the issue is ..
