I am familiar with the great power & volume of the bigger brother, the Landmark LM600 which I think is one of the strongest sounding heads on the market. I have never had the chance to try the LM300. So I ask, how loud/strong is? Could be enough for a quite loud old style R&B. blues quintet? I remember that the LM 600 was providing me enough volume with gain and volume up halfway. Thanks & regards.
