I also use ML 11As and I find them engaging and enjoyable at the level you prefer, but I understand that everyone's ears and experiences are different. I have also experienced better results after installing a line conditioner, and it's pretty affordable too (Niagara 1200).
thank you @elliottbnewcombjr for the information on the RLC-1, I have an older (at what point can something I purchased new be considered "vintage"?) preamp that never had remote capability and after all these years it would be nice to finally control the volume from my listening position.
