100+ Head-Fier
Just changed tubes to the Sonotone 5719 (single triode). Best sound I have ever heard out of any of my gear, including the fantastic Chord Hugo (for which I remain a massive advocate and rules for certain music - no doubt the Mojo too).
Wide soundstage; incredible rendering of instruments (mostly rock / Americana / blues / country-type tunes for me, plus a bit of funky stuff); you can hear the pick attack or fingers on guitar strings; great kick drums and nice crisp hi-hat and crash cymbals; fat but still punchy bass; warm but still crisp vocals. I'm sure I've heard a couple of things on tracks for the first time (probably new toy syndrome so pinch of salt).
As we know at this level, there is almost certainly a load of lucky synergy going on here, so FTR, here's the signal chain:
IP6 running Tidal > Apple CCK (always the weak link) > Moon Audio (Silver Dragon?) USB - mini USB > CDM (high gain setting) > Effect Audio 8-braid, single ended cable > Earsonics Velvets.
The difference is like the first time I swapped a single-ended IEM cable for a balanced one on my little AK120 + Glove A1 combo. It honestly sounds that much more open and separated.
Audition tracks:
Jude Cole - "Start the Car" (production style very much of its time, I.e. quite top-endy and not trying to win the loudness war like modern albums. This combo takes the edge off the top end)
Blackberry Smoke - "No Way Back to Eden" (the hand percussion at the beginning sounds fantastic. A modern album but with incredibly trebly production. This combo just warmed it up).
Eric Church - "Jack Daniels"
TFDI - "Slow It Down"
Jason Isbell - "Elephant"
The New Basement Tapes - "When I Get My Hands On You" (the hiss is on the original track!)
Daft Punk - "Get Lucky"
Gramatik - "Just Jammin'"
Obviously YMMV but my order of tubes preference so far is:
Sonotone 5719 single triode (don't forget to get the left and right tubes on the correct side)
Stock Sylvania 6111WA dual triode (tubes can go either side)
Sylvania 6021 brown label dual triode (bought after reading Lieven's fantastic headfonia article where they tested a bunch of tubes. Great example of YMMV and synergy, as I didn't like them as much as the stock tubes).
I have a couple of others to try at some stage, but leaving these in for now.
I've swapped mine to the Sonotones too. Loving them. By the way, I didn't pay attention to the L R configuration. What happens if one were to set incorrectly? I'm too lazy to reopen up the set to check. will it cause phase inversion or no sound? Thanks
