Melos updates worth it?


I just purchased the melos ma 333 and was wondering if anyone has sent theirs to las vegas for upgrades.Was it worth the $500 in your opinion?

I have a Maestro, I have opened up the cover and found horrible solder joins (which I re-flowed) chandged to amperex 7308 gold pin and noticed the unit does not have the photentiometer. I talked to this Melos update company 5 months ago (I lost their number since then) and they said it was hard to get the photentiometer parts. What is the update you speak about and can you list their number? I use the Melos MAT-180 as an amp. It works very well with the Maestro preamp.
mi3491, fone # was listed in my 1st post, here it is again: 702.248.6745. ask for brant (if he doesn't answer the fone!).

the maestro updated the caps from the sha-gold, so i understand; it also replaced the pho-tentiometer for a more reliable conwentional pot. since brant bought the company, they've come out w/a few other mods for all the melos product - one of them removes some mosfets & re-circuits the wiring thru the tubes. they can also do mods on the mat-180 amp.

Do you think the circuit is the same for the Maestro and the sha-gold except the caps upgrade? I know they have a update for the MAT-180 but the preamp is more reasonable to upgrade and I think I want to try the preamp first. The Maestro volume and balance pots have some gear play that makes them seem cheep. The do not react quickly with the remote because of the gear lash. I love the sound from the products even better now with the Audio Note DAC 1.1x in the system.
i believe the sha-gold & the maestro have the same circuit, but m.a.r. offers a circuit mod. personally, i'm waitin' for the new photentiometer wolume pot before i send 'em my preamp - i tink this will be a great mod. if ya don't wanna call 'em, try email at:

Unless they've risen from the dead, Melos has been out of
business for months.
