I have decided to get the little dot 1+ hybrid amp for my grado 325is. Might as well get a MF X-Can V2 as Dot1 is an OTL and don't take too well to low ohmage HPs. Also, I would say it's rather dangerous for your HP since it is OTL. You see, in OTL, there is no coupling traffo to protect your expensive HPs if ever it decided to throw it's tantrum. Bye, bye HPs.

The little dot 1+ is a hybrid and is specifically designed for low Ohmic HP's.
It is OTL just like the Bravo/Indeed/sunrise/HA10 thingies. These are all no more 'dangerous' than an Xcan V2.

You can't even say "it LOOKS good" can you? Not much info about it either apart from "Alan" who said "Apex arrived, connected Apex, now I'm listening to superb sound through my headphones, AKG 280, AKG K340 electrostatics". Yeh ok.... what about a look under the bonnet? It's probably a Cmoy under the hood?

:-*For people with more money than sense ? Interesting view , could you expand . I decided to get the Little Dot 1+ hybrid after a lot of research. To me after reading all the info and the cheap price tag it seemed like a good choice. I am open to any suggestions as it is all a learning curve for me. I will eventually get myself a Xcan v2 in the future , but this will have to wait until i can fully return to work after my mini strokes , which have hindered my cash flow. Cheers Paul

Cheers Paul Hi Paul As you will have gathered from the little "red devils", I was mainly stirring the pot. Briefly, a hybrid amplifier gives the best of both worlds. You get the typical warmth of a valve amplifier due to a higher proportion of even order harmonics, a lower output impedance, and wider bandwidth. Alex
