Mine came with counterfeit NE5532 op Amps so it's crap. Fortunately, they have sockets, so I replaced the fake NE5532's with real NE5532's and instantly notice an improvement in sound quality. If you hve ever measured a fake NE5532 you will see they have a higher noise floor and a poorer response. I had high hopes, but is the first and last time I will purchase another FX-Audio product.

Love your work Bro!

[@PrimeAudioReviews]

Thanks!

[@ghostjacker]

Great review. Got this when it 1st came out, and it had this hi-res sticker on the top. Which made no sense at all. Glad they got rid of it. This little tube amp makes my HE400SE sound perfect.

[@PrimeAudioReviews]

Sounds like a good combo!

[@spamcan9208]

I'm surprised you didn't compare it against the xduoo stuff. To me this is a much more compelling budget option than the mt 601/mt 602. As of now with the 15% coupon it's around $56USD. This costs less than the both of those models and saves you enough money to buy another set of tubes if you want to try rolling. I really didn't like the mt602 and returned it, even though it seemed popular. I figured I'd rather get the Vali 2 from Schitt for a few more dollars if I was going to get a hybrid amp or just save up and buy a real one. Is the gain stupid high like the xduoo? I also like the second set of switchable inputs and according the FX they have a circuit to suppress pops when plugging/unplugging.

[@PrimeAudioReviews]

Yes, it does have a mute circuit. I like the dual inputs too - it's especially useful for comparing different DACs. Yes, the gain is high, which is why I wouldn't recommend it for people who only use IEMs. You can circumvent that by lowering the volume of your source/music software etc but I don't like that compromise. I should have compared it with the xDuoo amps but all my videos are 'lite' versions at the moment while I'm catching up with/clearing my backlog. I will say that I don't remember hearing background noise with the MT602 even though it has higher output power. Regardless, the Tube 02 Pro is insanely good value at $56!

[@spamcan9208]

@@PrimeAudioReviews I don't mind a quick review. I can see why you wouldn't bring in another product, it runs the risk of being too long. It looks great for those curious about the tube sound.

[@Redxty83]

Love the video bro

[@PrimeAudioReviews]

Glad you enjoyed

[@jackalpha8844]

Thank you for your excellent review, I'm looking forward to buy this product but I'm having a question about the imbalance output while using it with sensitive IEM like the Dunu SA6, so I would love to know where was the volume to achieve the balancing? Was it too loud for sensitive IEM when achieving balance?

[@PrimeAudioReviews]

It's fine- you can just turn down the source volume to 90 or 95 percent and then you can easily achieve channel balance.

[@jackalpha8844]

@@PrimeAudioReviews so lovely, thank you very much

[@guillermoleoni]

Nice Review, thanks. Do you think that this can move some HE400SE and make a good combination?

[@PrimeAudioReviews]

Yes it will be good for the HE400SE.

[@gavingranado2146]

Might get this for a smaller print. Was planning on getting a hybrid tube with those toroidal transformers so I can use them with speakers as well. What do you think, will iems work with something as beefy as that ported through an ifi iematch?

[@PrimeAudioReviews]

Yes that will work fine.

[@Fckisnotrealnatowefc_nts]

Thanks for the video. Do you know how it compares with the nobsound ns-08e ?

[@PrimeAudioReviews]

I gifted my NS-08E to a friend years ago, so I can't really give a legitimate answer. However, from memory, I think the Tube 02 Pro is superior with better clarity and less background noise.
