Most dynamic headphones are very very sensitive relative to other designs.
When paired with powerful tube amps with will provide amazing slam, while still providing the body and tonal richness which is the hallmark of these amps.
The Pendant is compatible with many different 12AX*7 variety tubes. Changing to a 12AU7 will reduce the noise floor and increase the practical movement of the volume pot.
Whats great, is that changing this one tube will allow for better system matching/reduce noise floor as needed with varying sensitivity headphones.

Justin will a 12AU7 work as well with a Kenzie? I already have an adaptor and I could use more range on the volume pot I max out at 9 AM. If so do you have a recommended 12AU7 you like for the Kenzie, I will give it a try. I have lately been using an RCA grey glass 12SL7GT but am always looking forward to trying new tubes. I was lucky to find a stash of Tung Sol 1626s that should last me for a few years.

Any of the 12A_7 family should work fine. 12AU7, 12AT7, 12AX7. Varying degrees of amplification. The 12AT7 is my preferred of that group. Also check out 2C52.

Also, take a look at an octal to noval adapter for the 12B4A output tube. This will double your output power. Super inexpensive tube too. Justin USED to sell the 12B4A adapter setup and tubes on his website.

What is the 12A_7 responsible for?

What is the 12A_7 responsible for?

12A_7 is a single input tube on the Kenzie, Kenzie Encore that can be used in place of 12SL7/2C52 with an octal to noval adapter.

This is a photo of my Kenzie Encore with a n adapter and 12A_7 family type tube.....output tubes pictured are 1626.

The black device is a Bryston BDP-1 media player.

So is input tubes responsible for gain? I'm using 12AU7 on my Pendant.

It will will the correct adapter. I have a few great adapters. I’ll look tonight and post them.

Yes it is... input and gain.

Love your feet. The look super cool.

Hey guys as general heads up. I’m dyslexic as the day is long. You’re likely to get longer more expansive responses with a call. My new number is 949-636-9076. It’s listed on the site too.

Separately, the Pendant is a very quite tune amp when you look at measured performance. That said closed back orthodynamic headphones couple high efficiency and noise isolation. System matching and proper setup become even more important. Use of Ethernet over WiFi is a solid no go and consideration re distance to a WiFi broadcasting device is important.

Here’s a website that has some good tube data. The bottom of the page has the 12A_7 data listed by variant. Compare the amplification factor and that helps compare gain between tube series. I have a bunch of these 6201 tubes, which are basically 12AT7. They were made for some very old HP computer equipment. There are multiple tube substitutions and sometimes you can save money purchasing by using an extremely similar low demand vacuum tube.

Thanks I have used 12B4A and prefer the Tung Sol 1626. I don't need more power for the HD800S. Besides, once Schiit gets the Jotunheim R in production it will be hard for me to resist buying the Raal SR1a ear speakers. To afford those I would be selling my Kenzie, HD800S and might have to down grade my Yggdrasil to a Bifrost 2.

I like both output tubes, and switch them up from time to time. My problem is I have trouble selling my headphone stuff once I buy it. I just buy more of it. I thought about selling my Audeze LCD-X the other day, and spend all night listening to them......and decided to keep them.

Hey guys,
Just wanted to let everyone know that I will be posting my Mogwai SE (8/32/300 ohm taps) for sale in the next few days. If you are interested please reach out to me through a PM as I think it will go fast once it is posted. I will be using the money to purchase something else from Ampsandsound
