I just received my used ha1a i do have some ringing sound or watever it is when off /on other then that is working perfectly ok with my iems/hp. Now looking at rca clear top ecc82.

Cayin int he house.

Glad you like our HA-1AMk2. The ringing sound is normal if it only last a short while after power on/off or when the amplifier suffers shock and vibration (e.g., knock on the table), this is microphonic effect due to temperature change and minor vibration of tube filament (from shock).

You used the line out of N3Pro as source to the HA-1AMK2?

The HA-1AMK2 is a fairly powerful tube amplifier, and tube is known for background noise when paired with very sensitive headphones. I have customers trying to use IEM with HA-1AMK2 but didn't really work out very well. Wander what IEM have your tried with HA-1Amk2? Black background? Hiss free?

Nothing wrong with that. You bought the HA-1AMK2 before the N3Pro, so I assume you have a desktop source which should works better then the N3Pro line out, glad you like it for that purpose. which is a bonus.

Your IEM collections are mainly planars and est hybrids? These are all very demanding earphones, not surprised they don't hiss with HA-1AMK2, a nice workaround indeed.

Just bought an Motorola 5963 for this amp hope it turn out well. Is state is replacement for ecc82.

 

[muths66]

Anyone know i can use a EL84L to replace el84?

Hey all you HA-1A MK2 owners: A friendly reminder that this amp has preamp outputs that sound fabulous. In addition to headphone usage, I'm running the Cayin's preamp outputs to a 25 wpc power amp to Harbeth P3ERS speakers in a nearfield setup... and the sound is to-die-for good. I mean, HOLY **** good.

If you have a power amp and speakers (or powered speakers) around, you owe it to yourself to at least try out the Cayin's preamp outputs.

Aural Bliss. This amp transforms the Clear into something else. Swapped the EL84 to Mullard and 12AU7 to Brimar (Gold Lions coming in soon).

Chain: RPI-3B+ (MoOde Audio) -> iFi Micro iLink USB to SPDIF -> Schiit Bifrost Multibit (Coaxial) -> Cayin HA-1A MK-2 -> Forza Audio Noir Hybrid HPC -> Focal Clear

ur el84 is reissue model? is it very big difference compare to electro ?

There is a difference in the gain AFAIK. Have to turn up the volume knob till 11 o'clock position to get the same loudness with the stock tubes at 9 o'clock position. Tonally there's no difference in the two.

Dunno if my tubes are the reissue or not as I got em locally here in India.

I am thinking about adding a Clear to my collection as well. The more I look, read and listen, the more I think this headphone is the best performance to price deal on the market right now in the high-end headphone tiers. Also, I am curious to know what your thoughts are on the different tube rolls you have tried with the amp and the headphone and what sonic changes you were able to discern

Also, as a side note to the group and the IEM lovers specifically, I have to commend the iFi Audio iEmatch product. I have always wanted to use my IEMs on the amp but because they were really sensitive, the hiss was really audible. This thing is able to handle that problem and there is no audible hiss with my IEMs. Even my most sensitive pair, the Solaris from CA, have no audible hiss once I switch to ultra sensitive setting. This little piece cost me just 25$ from the second hand market and I dare say it's one of the best purchases I have made so far.
