Colouration is certainly the biggest problem with 'horns' after their
size - some colouration is easy to absorb and totally forget/ignore; some
isn't; some 'horns' are more 'coloured' than others. Whatever - all in
all, it's a small price to pay for an overall 'best sound' if, say, male
voices sound a bit quacky when you almost *never* hear a male voice
speaking on your system!

Lowthers and also those old Altecs that were ubiquitious in the 70s
give a valve trombone sound to die for:-)
