hmm, the tuba sounds like a great buy. 650$ and can be used on planars. i’m really curious about it
Kinda but not really. If you wanted something more suited to planar in that price range the liquid platinum is a better pick imo. The tuba is more suited towards dynamic

Copying this here… about the FX Audio Tube-03 I got yesterday.
Edit: Look at the reply.

It’s biggest selling feature, to me at least, is the ability to play nice with low impedance headphones. Much like Mapletree Audio, that is their niche.
I spoke to a couple of Mapletree owners who weren’t overly impressed. I asked them what they were using and they listed several headphones. NONE were low impedance?
From what I have read, these are Grado amps that can also drive the HD600’s pretty well. But there are probably lots of amps that will make the HD600’s and above perform much better.
There are a decent amount of tube amps that have low impedance outs at different price points, I think the overall performance for the price is what I think is stand out about the tuba, it’s got a unique sound
If all your headphones had at least a 200 Ohm impedance, would you buy or recommend this amp?
I still would yes, but I think that would also open you to many more options for tube amps that might meet a better price point or have a different sound
Fair enough.
There are a lot of tube amps I haven’t heard, so take it with a grain of salt, but IME I wouldn’t buy any tube amp for Planars alone. The Tuba sounds OK with the low impedance planars I have, and I still don’t like it with the Focals, but planar’s wouldn’t be the reason to buy it for me.
It’s still got a 5 Ohm output impedance, and I’ve always thought the 10x rule ought to be an absolute minimum.
If you want to drive low impedance headphones and want a tube sound, buy a hybrid, like the liquid platinum. If you want a pure tube sound, buy headphones with a higher impedance.

Thank you! I set an eBay alert so I got an email as soon as it went on sale. Haha. It went on sale in the evening and I bought it at 7am the next morning.
