Tube Hybrid versus a fully Solid State amp design.
The Liquid Carbon X will objectively perform better, and have a neutral character that sounds good with anything you plug into it... I have one of the original Liquid Carbons (serial number 47, if I remember right), and it’s still one of my favorite amps, a “deserted island 🌴 (with electricity) pick.”
The Tube Hybrid will be a tiny bit lower performance “on paper,” and you may hear weird squelches if your phone is nearby and you get a text, but it will deliver an emotional experience in spades, plus you can hold off the temptation to buy a whole new amp later because just changing the tube in this amp will affect the character and tone. The tube type in the CTH is widely compatible with many other types; the one included is a durable, long lasting spec version that will give you many thousands of listening hours before it burns out (I haven’t burned out a tube yet).
Either one is a great choice.
