hafler dh-101 pre-amp

Hey all, while at the record shop yesterday I came across this great little pre. It adds exactly what I've been looking for to my Music Hall 25.2.

The only question I have is.....does hit help to leave it on all the time? Could it get even better leaving it on?

Or just turn it off after a good days use?


All electronics sound better left on. With tube and some class a transistors this is not always practical. I was a Hafler dealer years ago and always left them on. It can sound even better if you ever decide to upgrade parts but this is not necessary.
