much love from Indonesia ♥️✨✨✨

Nonono not another impulse buy :p

this one or Xduoo mt-602?

Excellent, as always.

I have a been hearing great things about the Apos Ray Tubes , so much so I may try some of their Select 12AX7. But will they beat my NOS Tesla ECC83?

a upgraded power supply could perhaps improve the sound quality even further .

Grate review, Thank you sir

Thanks for all you do! Happy Holidays. ;-)

Pls review Fiio ft1 pro

As a true audiophile, you need to have a bad boy LPSUs on hand, to satisfy the tweakers among your viewers 😉

This is a real testament to the Apos Ray Select tubes!

I see no reason to buy it instead of the xDuoo MH-02

Please consider a review of the Emotiva BasX A2 Mini. I bought the Wharfedale Diamond 220s that you recommended in an earlier video. I am now considering the BasX A2 mini, Fosi V3, and Denon PM600NE. I prefer a warmer sound, so perhaps will choose the Denon. But I think you recommended the Fosi amp along with the SMSL SU-1 as an acceptable combination for the Wharfedales.

I love the looks of this little beast! Wonderful review!

No mention that this is an American store and shipping to Europe costs $35 usd not including possible customs + taxes?

WTF who cares for that tiny balanced amplifier?

Very curious to have this compared with an amp based on 6SN7 tube. Maybe apos will build a version with 6sn7. Great review!

Oh man. You should try the new Schitt Audio Vali 3 for $149. 100V rail on the thing.

would it go well with the Meze 105 AER headphones?

I guess then the next question is, what would a better power supply do for it.

vs MT604 please ? thanks

This is every high-end manufacturer's nightmare. Let 'em weep, mightily. 😅😂🤣 By the way, have a Merry Christmas! 🙂🎶🎶❄️☃️🍾

A 6922 is not normally considered an equivalent to a 12au7. Pin 9 on a 6922 is a shield...heater center tap for a 12au7. One is a 6v tube (6)922 the other a 12volt (12)au7. I guess they could leave pin 9 free floating? And technically a 12au7 can be run in parallel for a 6v filament. But the operating points are completely different between these 2 tubes if I recall correctly. I wonder which tube this amp is exactly biased to run more correctly. A 12au7 will have more distortion than a 6922 in most circuits. A 6922 has almost half the gain as a 12au7 type.
The 2 tubes are definitely on opposite sides of each other when biased correctly.

Anyway, good review as always. I was just a little perplexed about Apos choosing the 12au7 along with a 6992. I must be misunderstanding something. If anyone can help me understand better why these 2 types were chosen please explain. 👍

If I understood correctly, the audio performance of Fiio K11 R2R is in line with its price, they are modest.
I wonder if the audio experience from the K11 R2R is improved by using a tube amp, like the Apos Gremlin?

Outstanding as always Srboljub. I just got my Gremlin (w/core tubes only) and I love it. I agree with all your points on the core tubes. Unfortunately I was cheap initially and did not get the select tubes at the same time. I guess I'll have to get a matched pair of selects now. I also want to do some comparisons with the Gremlin against the Schiit Vali 3 and xDuoo MT-602. Thank you and keep up the great work.

How does it compare to the Aune S 17 Pro (Evo)?

How would this pair with the Focal Clear? I's like to warm it up a bit.

Great review! I’m thinking of buying Ibasso dc elite as i can’t pair it up with my mojo 2. Hopes that is a good idea

I love tubish sound and the ability to roll tubes to see how the sound changes. Given all this there is one major drawback. They don't last very long, so you need to purchase your favorite tubes and keep several pairs in stock. So you just keep paying into infinity with this type of equipment.

Merry Christmas Alisandro, great content as always!

I’ve had my Gremlin since the 7th, probably have a good 200 hours on it, all with the Select tubes in it. I haven’t tried the Core tubes yet.

I’m running Sennheiser HD650s and HifiMAN Edition KS headphones, Elysian Pilgrim IEMs with it.

I love this little beast!
