New Construction Roofing Nice and good!!!

No complained to this!!!

Powerfull, transparent but very musical, big bandwidth and powerfull bass. Tubes are not the most expensive and relatively easy to find. A high end amplifier without the price!

Ferrari black finish is beautiful but very fragile. The sound is very dependent of tubes (like all tubes gears)

Can't agree with the others who have reviewed here enough on the sound quality, which is extremely frustrating, since my amp has been with the engineer as much as it has been at home! Even though I use a mains conditioner and good quality cables etc, and the source and speakers are apparently well matched, it doesn't go more than 30 hours of listening before either a tube or a fuse has blown. Bias is all good and every time it goes back it is thoroughly checked and passes all the tests. I just wish it didn't sound so sweet, or I would send it back for my money back, but when it sings, it really sings!! Hoping that the engineer will find a reason for the poor reliability this time around, so hopefully I can have the amp back where it belongs, and that it will stay there for longer next time. Everyone thinks I am made for not giving up after 4 valve and 2 fuse replacements in 5 months, but you have to really listen to this amp to understand this madness.

Sweet Sound , excellent build

No cage for the front tubes,

I have used/ auditioned to many amps in 30 years period. In search for another power - amp , Graaf GM 100 become the alternative .I can say everything is excellent with that amp especially the unusually engineering .
Sweet midrange ,enough low frequency control ( with matching speakers) Bias is automatic so you dont have to play with anything exept the on/off button

Sound great, powerful, and beautiful to look at. The OTL engineering and archtecture is out of this world. All tubes.

Absolutely no weakness. Although it needs a man to lift it. Make sure the tubes are balanced.

Superb looking and sweet sounding power amp. Sounds so real. This must be the best power amp in the world. Vocal is warm, sound stage big, and brings out all the details, with great transparency. If you find one in the market, buy it. The finishing is Ferrari quality. A fine breed with plenty of power and finesse. This machine "flys" if the tubes are properly balanced. This will turn the Musical Fidelity solid state amp into a toy.
