Great to deal with. Very fast and easy. Excellent communication. Highly recommended

Very easy trade. IEMS were exactly as described. Very helpful with shipping options. Highly recommended!

My little dog Kaia. Been lurking here for a while, this is her sleeping on my legs as I type this 😀

GLWS! I'm listening to my Nautilus right now. I have the Tung Sol 6550 NOS and they are far and away my favourite power tubes in this amp - sounds so good!

Awesome! Thanks!

Quick question 😀. In the Nautilus, should I match the impedance of my headphones to the marked impedance on the outputs (at least as a starting point)? Ie. 300 ohm cans to the high z. LCD 5s to the 11ohm?

Thanks! That is very helpful - I will give it a try.

Thanks! I have decided to give HQPLayer another try. It was working with Holo Audio Red as the NAA endpoint. I tried to use the demo of version 5 but that didn't work so I rolled back to my version 4 but that had now broken by installing the demo of 5. So I started from scratch with version 4...

Good question. I suppose my thinking was: I can add OS to a NOS DAC but can't remove it from a DAC that does OS internally. So I can have both. I like how it sounds both ways. :wink:

My dac is a holo spring 3 and doesn’t offer over sampling. I really like the sound of NOS but also like the upsampled sound from HQPlayer. I just find HQPlayer itself clumsy and awkward. I also don’t really like having a computer in my audio chain as it nice to get away from them sometimes 😀...

Thanks for that I will have a look at the Audiobyte stuff that sounds like what I am after!

I have played around with HQPlayer a few times and finally bit the bullet and bought a copy 6 months ago. I have repurposed an older Mac Mini now running linux and HQplayer Desktop. It works fine, I can upsample PCM ok, not really enough grunt to upsample to DSD but that’s fine. But I have a...

Interesting. I will try that! Also wondering about how the rca and xlr inputs work on the back of the nautilus. Would it be ok to have my Dac plugged into one and the turntable into the other? Would having both playing at the same time (accidentally) damage the amp?

I have tried the JJ KT88s sorry - so I couldn’t say. I was looking for something that might sit in place of NOS Tung Sol 6550. I haven’t tested them back to back yet but will at some stage. For now I have changed the whole tube complement in one go. So I went from NOS 6050, Brimar 6060 and...

New tube day

Thanks! That’s super helpful. That’s probably what I did. Doh!

Just went to listen to my Nautilus and found both fuses had blown. Replaced them and all is fine. Just wondering what could be some of the causes of blowing fuses. Trying to make sure I dont have any systemic issues! Thanks!

I’m so confused - lol I had NAA working. Then I upgraded the OS and now NAA doesn’t work. Roon is still working, but its getting a bit frustrating. I would love to know how to setup the RED (and potentially HQPlayer) so that I can get 1mhz+ PCM or 512DSD to the my Holo Spring 3 I have a Mac...

Received mine last week. Can’t wait for a manual! I got it working but am super confused! I am trying to use it as a NAA endpoint. Mac Mini running HQPlayer —> NAA over Ethernet —> Holo Red —> via usb —> Spring 3 Max upsampling seems to be 768k pcm It will only output sound from the...

Thanks for sharing this! “Knowing what you're looking for, and then, what you're looking at, is two thirds of the battle” flicked a switch in my brain. I am starting to fall down the rabbit hole. It feels like maybe the more you know the less it costs!

Thanks - that is super helpful!

Quick question for everyone. What is the rule of thumb for which impedence tap to choose on the amp. Would it be the closest to the impedence of the headphones? i.e. if the heaphones are 40ohm I would choose the 32ohm tap?

The are both really great - well done! Love your passion!

I see you have a sit-3. That is a cool amp! Do you use it with headphones?
