(This German buyer have bought Mpingo disk block MD-03.
Then, he sent his review to us, and so uproad here with his permission.
He bought also Reso-bell large and MD-03 & MD-01 again on 2021.)
the parcel arrived without any custom issues incredible fast.
And the sonic improvement is absolute stunningly.
I use the MD-03 as a device for resonance control on top of my loudspeakers,
on top of a power filter and in the fuse box on top of the electric meter.
The sound is fuller, much more powerful and at the end more real.
This are keepers.
Thanks a lot...
