Yea I would say its less forward sounding. These are hybrid amps, so they will not be the full tube experience. It also depends on the tubes used. With the phllips NOS it was definitely on the warm side with smooth treble.

Oh, sorry, one more question. Does your MT-601 have a strong click when you turn on? And what is the constant voltage at the headphones jack output? If you have measured. And is there any protection in MT-601?

 

[SoundGuru]

Yea but this doesn't always happen. I am not sure of the voltage havent measured.

Not sure what you mean by protection? The amp gets very loud and there is no limiter. I wish the amp gain wasn't so high, so that there was more of a range for suitable volumes.

They are Mullard reissues, standard current production Russian tubes. 80€ per pair is too much.

I have the opportunity to buy these valves on amazon for my TA-20 ABOUT 80 EURO PER PAIR
https://www.amazon.it/dp/B01HQYWB7M...olid=1EIC48SPBXWFV&psc=1&ref_=lv_ov_lig_dp_it
you think it's a good deal compared to the standard tubes I have on my TA-20.
Thank you

Yes, the Mullard reissue 12AU7 are fine, many enjoy them, here are some good places to get them that have a fair price, and I've bought from them with 100% satisfaction before:
https://www.thetubestore.com/mullard-12au7-reissue
12AU7 Selection: https://www.thetubestore.com/preamp-tubes/12au7-ecc82-tube-types
https://www.vivatubes.com/new-mullard-12au7-ecc82-reissue-vacuum-tube/
12AU7 Selection: https://www.vivatubes.com/new-mullard-12au7-ecc82-reissue-vacuum-tube/

12AU7 Selection: https://tubedepot.com/t/tubes/preamp-tubes/12au7-ecc82-cv4003-5814a

Some of these sellers also have ratings or descriptions for their tubes to help decide what to purchase. Either in the tube listing itself, or in tabs above, look around and discover what they have to offer.

And, you can see their prices vary for specific tubes, so I shop the the lowest price from vendors I trust - that is why it is a good idea to have multiple suppliers, they all get different "deals" on parts themselves and sometimes even the best dealer doesn't get a "best price" on their stock and have to charge a bit more.

That is why I shop around, but I don't always keep strictly to that "best price" criteria, as some dealers are closer and can ship quicker, or offer other services like balancing gain within the tube and externally, and those dealers can cost more.

If they don't off balancing gain options, ask them via their support email if they will balance pairs/quads of tubes, and if they can pick your's for balanced gain within the tube - some amps use only 1 tube so you can't gain average between 2/4 tubes.

Good listening

What is the difference between the Mullard 12AU7 reissues and the originals?
still is the price high for the Mullard 12AU7 reissues?

MT-602 being fed from a SMSL SU-8 (thank God for the volume control) in turn being fed from a NAD C542, 1967 Sylania's and a pair of Takstar Pro82 should not sound this good...
Listening to some Black Light Syndrome

for the xduoo TA-20 these valves at 50 euros the pair: https://www.amazon.it/dp/B09GB9KD4J...lid=1EIC48SPBXWFV&psc=1&ref_=lv_ov_lig_dp_its are a good improvement in your opinion?
