i am looking at alo cdm, wa8 and tur-06 for my iem 16ohms 114 sensitivity.
anyone tried at least two of them before?
thanks.
I own a CDM and spent some time trying a Wa8 last week.
The CDM is great for portability. It's not smart-phone portable but I carry mine strapped to a FiiO X7mkII either in my hand or bag with no issues, and you could certainly get them into the pocket of a winter coat or even cargo pants.
Tube rolling is fun (yes it does make an audible difference - although more about your own tonal preference than actual sound quality).
As someone mentioned above, the amp adds real depth, punch and, especially with the tubes, warmth. When I got mine I was still using an iPhone 6 as a source, so adding the CDM's amp and DAC with a good pair of IEMs was life changing!
The Wa8 sounds AMAZING. It weighs a tonne so isn't portable. Rather, it's transportable thanks to the battery and more manageable size than desktop amp.
All of the reviews have said the battery life is very short.
So the Wa8 is incredibly small and transportable for a world class tube amp, but bloody heavy and short on battery for a 2017-gen on-the-move music device. It depends on which way you come at it.
There have been complaints about the Wa8 not powering demanding 'phones, but it was fine with my IEMs.
The sound blew me away and I will be buying one in the next couple of weeks. On sheer sound preference, I'd take the Wa8; but for my lifestyle and the portability, I'm glad I have the CDM. It's a fantastic product.
