Has there been any silent revisions? Looking to pick one up again to cure my HD800S. Its the only amp that gave me goosebumps! Once you hear a proper 300b, its hard to be satisfied with anything else.

Very true on the HD800S. There is some kind of magic or witchcraft with this pairing.

I'm very surprised that the 6SN7W metal base tube didn't work out for you, but I found it to be a massive improvement over the previous Shuguang tubes, the Psvane CV-181-TII, and the 3-hole Sylvania bad boys I had. Then again, I did managed to get a NOS pair, but even the not as new pair I auditioned from my friend sounded fantastic. Coupled with the Psvane ACME 300b, I found the on my Audeze LCD-3F headphones, I had bigger soundstage, clearer air, faster/snappier more-defined texture, sweeter midrange voice, and tighter bass. I didn't have as much boy in the midbass and bass as I'd like, but the PS Audio Stellar Audio Power Plant 3 and the Sablon Audio 2020 Panatella Reserva USB cable added that while improving everything all around. Right now, I can't even listen to the Chord Hugo TT2's stock headphone amp without feeling like I'm missing a lot of special sound when I go through the HA-300 instead.

Same thing goes for me. I can't listen to my wa22 anymore... ha300 is in another league of course. I was also surprised that I did not like the 6sn7w tubes, but like I said the new owner of those tubes will definitely like them. I'm not worried at all. I'm glad you managed to improve your sound. I think one of my biggest upgrades lately apart from the driver tubes (6F8G) is my new cable for my headphones that I ordered from Trevor. He works for norne audio, and quite recently they released the brand new silvergarde S4. I highly recommend this headphone cable to anyone, I immediately noticed a difference the day I received it. Much much better instrument separation, bigger soundstage.. the s4 is not a cheap cable but it's definitely worth it.

Did anyone roll 7N7's or 6J5'S in their HA300? I read that 7N7 is electrically fully identical to 6sn7 apart from the loctal base, and the pin out is different. I plan on getting adapters on ebay and roll some 7N7'S while they're still cheap. For 6j5 I need 4 of those, two for each socket. I'm still unsure if they could work in the ha300 even with adapters.

I wonder if I will someday switch also to a Ha300.
Currently I don't have the space for it and I don't know if it can match the satisfaction of the Ha6a with EDM.

Maybe with some EAT 300Bs


Also +1 to Norne cables. Can't wait to receive my new load

Do you have a link for his cables? I'd like to get new cables for my Lcd-3 and my Aeon 2 closed

It took him some time to update his website but he finally did it

He's been extremely busy and it's been a few months that I've been trying to order his XLR cables. But I highly suggest patience when dealing with Trevor. His products are worth it.

I just got some Psvanne CV181 and they have a static low level. Are they bad? anyone have this experience. Vendor is claiming they need warm up, but this seems no good....

I'd give it a few hours warm up and if it still there, then I would demand a replacement or refund. Happened to me before and I just returned it to the ebay seller at my expense, but I did get a refund.

Was bit too excited swapping dacs and forgot to turn it off! Good thing Cayin provided 2 spares!

I had those before and never got the static low level. Doesn't sound like a good pair

 

[Sampajanna]

By low level I just mean it isn't super loud. Just a constant, but very audible static hiss...

Yeah, mine is dead silent. Only time I can hear anything is when I select the XLR as source and XLR out to my Audeze LCD-3 with nothing playing and the volume knob at 99 or 100%. Everything below that is dead silent.

I hear there are two fuses in the HA-300. How did you access them? I know there are audiophile fuses and I wonder if they'll make a difference.

Just the one located there.

Yeah, those "audiofool" fuses are a big waste of money and you're just paying for the snake oil look of them. I'd rather invest more on tubes!

I remember looking at that. How do you open it up?
