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?

Is there a website that describes Melos upgrades or gives current service info? melos.com is still non-functional. Btw, anyone who's interested in this topic might want to search "melos" on the tube asylum page -- I remember reading some posts last September/October about Melos service nightmares from people who said they had negative experiences in dealing with Arizona. I have no personal experience, but I remember the posts because I own an MA-333. I'd be interested to see posts from people with first hand experience.
jbaxley,

no, the latest melos audio restorations does not yet have a webpage, but they said it would be soon. i suggest ya call 'em up to get the info...

re: service nitemares, try audioreview for unbelievably bad experiences! it almost made me shy away from 'em, but 3 separate dealers' comments about the sound quality - 2 of them who knowingly may have lost potential sales cuz of it - made me take the chance. it also helped knowing that there was a gnu owner. the 1st owner was in nj, the second in nevada, the present owner is also in nevada.

my experience w/the present owner has been reasonable-enuff. he completed a full music-director upgrade that was only partially done by the previous company (unbeknownst to the previous owner of the preamp), & gave me a reduced-rate price.

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.
