Sorry, I did not mean to unsettle you.
Actually I do like Lewitt mics a lot. I have the big drum case (7 mics) and a LCT 550.
Of course you can make very good recordings with the LCT 440 Pure recording sax, guitar and vocals. I would prefer it to a NT1.
But it is more dependent of the room than the SM57. So, if you lost your SM57 and your bedroom sounds okay, go for the Lewitt.
For what it's worth:
Of course the LCT540 costs almost three times as much, but the Techgraphs are very similar.
