So any 0.75A 250V fuse should work?

Thanks for your persistence on finding this information! I really like this amp so I kept it despite the fuse issue. Good to know it's easily resolvable myself.

To my knowledge, any 5x20mm 0.75A should cure the issue.

Going to write up a review as well here, but in the mean time...

Great review. As an owner of the TA-30 I cannot disagree with much of this. I do really like what it does to the sound signature of the Utopia but I do agree with you that perhaps it comes at a small loss of detail vs alternatives.

I would say that the introduction of a good external DAC makes a difference not only on a sound quality front but also for quality of life due to the high gain rendering usable range of the volume dial quite useless

I've been pairing the Ta-30 to the new Topping D90MQa and really liking the combo and to @XeNoNF50 comment, using the pre-amp volume control on the D90 allows you to bring the gain down on the Ta-30 to the point you have more usable volume control on the Ta-30 itself. That and a couple of tube upgrades and you have one heckuva amp for the $.

I was under the impression that the 12AU7 tubes are preamp tubes only and that the TA-30 has a solid state output amplifier. Never heard of 12AU7 being used for power amplification, much less the amount of power the TA-30 has. Am I missing something here? I think xDuoo calls them preamp tubes but I don't remember any mention of how output power is handled.

12au7 is a pre-amp tube in the bulk of the Xduoo line-up. Some models (Ta-03s) have tube output stage while other (TA-30, Ta-20, etc) have a solid state output stage.

looks like a new one is coming out - Ta-10R pictures have started to surface - don't have details yet.

Currawong stated in his review that the 12AU7s were the output tubes. That's why I was questioning if that was true. He needs to correct that point in his review so as not to confuse those who have limited knowledge about tube equipment.

Agreed, with nearly 4 watts of output power, there simply is no way any of the 12a_7 series could muster that.

I should have mentioned it was a hybrid, my bad. This is the kind of mistake I make as a result of not scripting my videos.

No worries, we've all goofed a time or two, it happens, you clean it up and go on. I know I've made more than a few mistakes along the way.

Been told I have one on the way so I feel another tube rolling experiment coming on.

Hi, newbie here.

Im really interested with Xduoo TA-05, but there's no mention regarding if it can be use as pre out to active speaker, and there are two sets of rca in the backside. I really need the headphone hybrid amp that also can be use as pre out. My other option is SMSL SP100 but it dont have enough power to drive R70X. In case someone own the TA-05, mind to share the experience and also answer my question regarding pre out.

Thank you

*sorry for my bad english

Both of the sets of RCAs on the back are inputs, the Ta-05 does not have a pre-out. To have a pre-out, you need to go to the Ta-10. For the record The Ta-20 and Ta-30 also have pre-outs, The Ta-01b and Ta-03s do not.
