Dear Nuprime,

I hope many will be in agreement with me in asking you to include a subwoofer out in your future, especially budget (<$1k) amplifiers.
I can see why some, including you, may consider the amp in the subs as being of a lower quality than what you provide, but being on a limited budget I think it is better to have a decent active sub rather than no sub. For the last 15 years I considered a pair of bookshelves and a sub a far better option (my value for money) than a true full range pair of speakers.

I am in the lucky situation to have an excellent sub with speaker level input but 1. it's getting old and 2. not many makers still offer this input. External crossovers are rare and I suspect they'll never be a 'thing' one could reliably find on the market.

Thank you
