New Head-Fier
First, before you read this, keep in mind that I've been going at this for a week now and it has made me pretty angry. I'm very technical and have gotten big into audio just a few months ago. I thought it would've been a great idea to get a tube amp since I've heard nothing but good things from them. I swapped my tubes to the rca jan 6as7g and the tung sol 6sn7gtb from stock. If I need to get access to something just tell me what it is that I need to test with if it seems worth it to me I'm willing to test with it. I'm currently in college for computer engineering and have a background in cybersecurity and networking, I build and troubleshoot computers as a side job. All of my cables are less than 6 feet, I did all of my testing isolated from my powered-on monitors, cables weren't everywhere when I tested it. I'm 99% sure that my amps are working correctly
Hi owner of the infamous HD58X/DT770 80ohm, DV336se tube rolled, Magni 3 Heresy, Focusrite 2i4 gen 1 and around 50. Currently my DT770 is not at my house
I ran into an issue with the Modi 3+ after upgrading from my Focusrite 2i4 where after purchasing and using a Sescom A/B switch I discovered that there simply put was no difference that I currently can't comprehend with this setup
After discovering that the Modi 3+ didn't meet my expectations when purchasing it I used the same sescom switch to test the difference between amps on the Input line from my microphone(Shure SM58). being that the Microphone is already an analog device I suspected it to be at the purest level of detail that I can currently drive. I plugged in my darkvoice and Magni directly from the unbalanced monos using a y splitter plugged both amps into the sescom A/B tester and turned the Direct Monitoring to input. When talking into the microphone there was a complete night and day difference between amps. But if I recorded said audio I just spoke with it would sound muddy and different on either the Focusrite's USB interface or the Modi 3+ directly to the amp
Here's the path I ran after discovering that my Modi 3+ couldn't drive my dv336se. I did this to confirm to myself that the Focusrite did indeed not color the audio such that the audio would be easier to pick out
PC -> DAC ->RCA to XLR -> Focusrite -> y splitter -> both amps-> into sescom a/b switch -> headphone
I've also ran the tests with and without a y splitter, unplugged the devices, and ran the chains separately. I've swapped to 4 other computers and ran the troubleshooting tips off schiits website
After much testing, I concluded that the Focusrite didn't color the Microphone input as it was used directly as an analog signal. The Modi 3+ sounded identical with the Focusrite in the loop or without it
I'm aware that XLR uses 4 volts, but I believe that shouldn't affect performance since 2 Volt in 2 Volts out when using 2 XLR to rca cables
I haven't returned the Modi 3+ yet (still got a few more days before I have to ship it), I've ordered a Modius and I'm hoping that fixes my issue (but it's back-ordered until May 5th for me). I'm aware that it shouldn't be eq levels of difference, I believe that is pretty obvious.
The performance that I expected was that vocals would be more warm, open, and it would indeed color the sound to sound slightly distorted in a pleasing way. From what I think is happening is that either I just got unlucky with my Modi 3+ or am I just expecting more out of my tube amp. But what really is driving me mad is that my Focusrite 2i4 using a mic sounds like I'm talking in a hallway, even with someone else talking into it same results. But when I record the vocals and then do playback on the modi 3+ the hallway effect completely removed (Audacity). I feel like my conclusion is completely right but I'm still stumped that all of Reddit just took a dump on my posts
But in the meantime
What techniques have you used to test the difference between tube and solid-state amps
And I've also tested my tube and solid state on the rca cables from my gamecube just to test it on there, my 4k samsung QLED tv's optical output, my labtop, a different desktop, and my phone. I've also tested it with it grounded down to the same outlet as the pc, DV336se without ground same outlet but pc has ground, and 2 different breakers with and without ground. That and I did for a period of time tried messing with eq just to see if mids got louder when bass matched volume
With all of that testing should've a normal person heard at least some sort of difference or was I going about it the wrong way
