Schiit Freya+ Tube Stage is Silent
The site won't allow me to update the post, so I thought I'd give an update here:   Swapping in new 5687s made the situation worse (no output at all), so I swapped in all 6SN7s and the passive and JFET stages came back, but the tube output did n... 
Schiit Freya+ Tube Stage is Silent
@koestner Help me understand the logic? The pass and JFET buffer stages work with the crossover in place. What about the tube would be different, other than putting out +12dB worth of voltage?   
Schiit Freya+ Tube Stage is Silent
The balanced output from the Freya+ is plugged into a Marchand XM44-1FB    Electronic crossover, 1-way, fully internally balanced. The Marchand XM44-1FB connects to 2 Schiit Tyr monoblocks. The single ended output from the Freya+ plugs into a Rhyt... 
Claude’s amp upgrade recommdation
The issue with all of these responses related to generative AI is that nobody mentioned needing to train the AI .They don't know what good looks like. You'd need to tell them what good is. I have a highly trained Claude project and here's the res... 
A New Integrated Amp
Agreed with cdtd. If you end up down the path of the Maggies, the 1.7 series is ideally paired with the Cronus Magnum III, along with a separate and self-powered sub, like Rythmik F12 or comparable.  
Bricasti M1 Upgrade to MDx
There are 3 upgrades:  MDx - $1250 - provides for native DSD256 with USB, and greatly improved Master Clock Sync. M1 Series 2 - $2500 - replaces most of the chassis parts to larger ones to house and the larger power supplies that are both foun... 
Why don’t more members post their systems in their profile?
I created a detailed inventory for my rig and then created a GPT to provide advice about it. However, I probably wouldn’t provide that level of detail in an online forum, because it feels risky. Edit: I suspect someone could note a number of the ... 
use of ChatGPT for HIFI
Hey, @emergingsoul  - Thanks. I have a typo in my comment. It's a 12AT7, not AT12. As a follow-up, I previously went down the path of MELZ metal plate 6N8S tubes in both stages (before the adapters and tube changes to Telefunken and Sylvania) and... 
use of ChatGPT for HIFI
I built and trained a GPT on OpenAI's 4.o using Ivy League Master's courseware, as well as consulting back and forth about what it did and did not know, ultimately rolling the info back into the GPT's base training. I gave it my detailed system in... 
Looking for a new DAC
With the myriad of responses you've already received, mine may not provide a whole lot of value.  My prior system consisted of Magnepan 1.7s, a Rogue Audio Cronus Magnum III stereo tube amp, the BlueSound node (2, then 2i, then n130) and outboard... 
Streamer, no DAC please?
I agree with yyzsantabarbara. The Lumin U2 is an excellent choice. especially with its upsampling capabilities. I wish it were in Op's price range.  
Best Music Streamer to pair with Rogue Audio monoblocks and Pre-Amp
I have a Node 2i USB connected to a Schiit Audio Bifrost 2/64, Schiit Tyrs, and Magnepan 3.7i. I cross over at 80hz between the Magnepans and a Rhythmik F12SE. It sounds magical.   
Project (Pro-ject) X1B
The site and some of the reseller sites are inconsistently telling me they had the Ortofon Red, then the Sumiko, and now something that is a rebranded Ortofon red. Which is it for sure?  
Upgrade from Schiit Bifrost 2?
I eventually had to spam one of Jason’s live streams to get the attention I needed. Once in touch, the process worked. Since this time, I’ve replaced the CM III with a pair of Schitt Tyrs and the Freya +, modded with upgraded caps, and rolled tu... 
power amp ideas for less than $3000
Upvote for the Schitt Tyr monoblocks. I’m using them to drive Maggie 3.7is.
