Schiit Lyr Tube Rollers - Page 163

post #2431 of 10949
I just ordered this interconnect. I currently use the excellent Supra Sword ISL anniversity ics. I choose it after rolling many other cables. They're not cheap though, around $700 for a one meter pair.

But I just ordered this Aural Thrills active bias cable, and will give it a try. I ordered the upgraded teflon plugs as well. It's very reasonbly priced.
I'll let you know how they sound.

I initially thought that having a mutual conductance tester which not only checks emissions and leakage but transconductance as well would do it. Those, such as vintage Hickok's, are available in the $300-$500 price range. Unfortunately, tube testers are designed to find bad tubes not to match or determine the gain and noise characteristics of good tubes.  These tasks need much more expensive equipment including curve tracers, RMS meters etc. 

However, it turns out there is a much more applicable approach to this which does not rely on this type of specialized investment. Ask yourself, why you are testing and matching the tubes in the first place. It is to establish that when you input the same signal in both channels at various levels, it keeps the output signal balanced between the channels.  As our Lyr tubes are dual triodes, there are 4 amp sections (2 each channel) that need to match in order for the outputs to match. This can be easily tested with computer-based electronic test programs (ex: Fuzzmeasure Pro) using the Lyre itself. 

Therefore, I decided to not purchase a specialized setup but periodically check using software and buy from reputable dealers.  
Great post! Yes matching and balancing is crucial for good clarity, and holographic sound staging. Tubes need to be tested for gas leakage, approx 10-15% of the tubes I get from Russia, Ukraine, etc... fail this test.

Not sure if I can ask things like this in this thread but I'm curious what you guys are finding for the best sources for your Lyr if you don't have a DAC? I've tried my iPad, my Droid, and a couple PCs but I'm not sure if there is a better way until I nab a Bifrost smily_headphones1.gif

Sure, there is the Modi, a great little DAC, now either USB or optical inputs. I am using the Modi>Lyr 2>HD650's with excellent results. I am planning on stepping up to a Bitfrost soon, or perhaps going all the way to a Yggy. But I am very happy with my current setup.

I am planning on getting the gungnir to replace my pioneer Reciever, however the yggdrasil and Ragnarok are making me reconsider. I have what I do not need and need what I do not have...Will the audiophile in me ever be happy? And will my wallet ever forgive me lol.

New to tubes, can someone help me with a suggestion with tubes for the lyr2, I am using the audeze lcd2 headphones and would like to try some new tubes as opposed to the stock ones.

post #2437 of 10949
Anybody looking to buy a new DAC should consider a tubed one. Just like on the Lyr, the tube output stage, with the right tubes, can be excellent. More musical, better sound staging, more flow.

Here is a nice little unit, I've been looking at upgrading my office system to - the Lite DAC68

$799 shipped not bad. And uses 6922 tubes!

IMO, Orange Globes made in the 60's with O getter sound the best. They are great for rock and electronica music. For female vocal, they are a bit too forward/in your face sounding.

Are they the 6922 tubes? how is the bass with these tubes?

No, they are 6DJ8 / ECC88. Bass is not bad.

One thing I'll admit I'm confused about is how a DAC interfaces with the Lyr. The Lyr has analog RCA inputs so what good does it do to utilize a digital source to send it through an analog amp? Or am I looking at this completely wrong?

Just think of your Lyr as an integrated amp and your DAC as a source. The Lyr takes the analog output of your source (laptop)>DAC >analog signal output>Lyr amplification of analog signal>Transducer (headphone, speakers).
post #2442 of 10949
Ahh, so the DACs job is to send the amp the cleanest signal possible?
post #2443 of 10949
^Yes, in a perfect world that signal would then be passed on as is, without the interconnect, amplifier, headphone cable/speaker cable altering the sound.
post #2444 of 10949
Awesome, thank you! And I know this is a Lyr thread but is $230 shipped good for a used non USB Bifrost?
post #2445 of 10949
^^Yes, that is a great price, especially since you can upgrade over time to the Über Analog and USB INPUT. Enjoy the music!
