Vacuum Tube D3A Parafeed Headphone Amplifier Includes NOS and matched Valvo D3A tubes. The D3A tubes are loaded with a cascode DN2540 CCS. The DN2540 mosfets were matched so that both tubes draw identical current. Works equally well with low and high impedance headphones. Initially used LED...

This is a DIY headphone amp using the 6C45Pi tubes, similar to the Papa Rusa or Bottlehead Mainline amps. It has a switch for HiZ and LoZ (12:1 and 8:1 ratios) In terms of performance, it has alot of power (500+ mW on LoZ, and over 200mW on HiZ) The frequency response is within 1dB between 20Hz...

Matrix Audio element-i DAC/Headphone amp/Streamer Unit is in excellent working condition. Includes all original accessories including manual, box, remote, cables. I recently changed to an all-in-one streaming amplifier so no longer need this. Price includes free shipping in CONUS

Echoing all the other comments here, this is a beautiful build, congrats. I have been looking to build a parafeed HP amp based off of 5842 tube for a while, and more recently acquired some 6C45PI tubes so may build this one instead. I purchased a pair of Sowter 8665 transformers for the...

Custom built EL84 headphone and speaker amplifier. I built a few of these and sold them in the past year, this is the final one and I will not be building any more. The output transformers are by Transcendar, same brand that is used for ampsandsound and the ZMF Pendant which cost $2K for a...

Audeze LCD-X (2021 Version) Leather-Free Premium Package Excellent condition. I am the original owner and purchased about 4 months ago. Great headphones, I just have a fairly high powered tube amp so don't really need the efficiency. Comes with original box, case, balanced and SE cables...

Bump!

Audeze LCD-X (2021 Version) Leather-Free Premium Package Excellent condition. I am the original owner and purchased about 2 months ago. Great headphones, I just have a fairly high powered tube amp so don't really need the efficiency. Comes with original box, case, balanced and SE cables...

I'm definitely not an expert but does a 12AU7 have enough drive capability for a 300B? I know atleast with the TU-8600S that it had 2 stages of gain. That said, it was also possible to use the 12BH7A with the Neurochrome DG300B so perhaps its fine.

Hi Jamie... after building both the Mainline and the TU-8600 (I don't own either anymore though), I would recommend the Elekit. I think at their prices it is a much better value. The Kaiju has what seem like rather small EI transformers, which the Lundahl are likely of much higher quality. You...

I built a few of these amps and offering them here at basically cost. Not looking to profit off of these, purpose of building these was to experiment with different power supply and transformer configurations. They are all the same circuit (RH84, which is fairly known as sounding great) and have...

@KPzypher good for you! It would be a shame though that you would limit such an amp to a single pair of headphones. I don't have the Pendant and have not heard one, but given that it is made by a reputable designer and specifically for headphones, I have to assume that unless its faulty it...

I'm selling off some of my EL84 stash, all NOS and attractive prices (IMHO) If you were looking to try tube rolling in your Pendant, this may be a good opportunity. (hoping this does not violate forum rules) Post is here...

A bit late but wanted to thank @DecentLevi for arranging this unique meet and everyone else who attended. @Brainiac9000 brought some serious gear ... really impressive! I had a chance to listen to a wide variety of headphones I've been reading about for years on my 45 SET. I really really...

I plan on arriving at around 11.... I can try and pick you up if I don't have any delays. PM me your details. I can't still till 4pm.. I'll probably hang around for 2-3 hrs.

I am looking forward to it! I have heard alot of gear and lately built some more but in the end I find that my ears simply are not that refined to hear the nuances and subtleties. I'm most excited for folks to spend some time with the amps and DAC I built and let me know their honest opinion...

For anyone in the Seattle area and interested in hearing the Aeolus with some tubes, I will be attending the Jan. 25 meet (the DecentLevi one) and will bring my DIY 45 SET amp. The amp has NOS Sylvania 45 power tubes, Western Electric 417A drivers and Amperex 5AR4 rectifier.

Awesome gear @carlman14. It will be great to compare impressions of the Mogwai to my DIY tube amp. I'll bring a ZMF Aeolus and Hifiman HE5SE..... I've never heard the Atticus or Auteur but either would be really cool to compare to the Aeolus

Here are some photo's of the 45 tube amp and the RJM Sapphire. The 45 is built around the Tubelab SE-II PCB. It is a transformer based circuit. The tubes I ended up using are Sylvania 45 power tubes, Western Electric 417A driver tubes and Amperex 5AR4 rectifier. Power tx was custom ordered from...

Which mod do you have on your HD650? I only did a basic coin mod and have been thinking about the KISS mod but have not gotten around to it. I actually enjoy the 45 SET the most with the HD650... it may be worth bringing your pair so that you have a familiar baseline.

Count me in as well.. I can bring my DIY gear: 1) Tubelab SET 45 amp 2) RJM Sapphire Class-A headphone amp 3) Twisted pear Buffalo 9038Pro DAC I'll bring an HD650 and and Hifiman HE5-SE.... maybe the ZMF Aeolus

Let me just put this post here: https://www.head-fi.org/threads/zmf-aeolus-impressions-thread.890441/page-64#post-14883758 Regardless congrat's on your Aeolus and I hope you enjoy them!

A cost efficient option for a high quality cable is to build your own. These are 2 I built for the Aeolus. One with Switchcraft mini-XLR and Neutrik 1/4", the other with Furutech mini-XLR and Neutrik 4-pin XLR. Canare cable for both.... cost about $30 in parts, a bit more if using Furutech...
