I have little experience in audio and I am looking for advice.
I am interested in 2.1 audio. Currently have a NAD218 amp connected to a simple denon 379 (as a preamp) to drive my RtiA9 towers.
My questions are:
1) will be there a noticeable improvement by replacing my little denon with a dedicated preamp?
2) I have limited options where I live. My options are: (7 year old) Sunfire grand theatre 4 (at US 800) or a Marantz pm8004 using it as a preamp. The reason I am considering marantz over my denon is that in my denon does not have a main zone preout but a zone 2 preout, leaving me with no tone control, no sub control, no volume knob control (It is operated only via remote control).
The sunfire looks like a great preamp but I will not be using all its functions. I am just looking for 2.1 and it seems overpriced for being 7-10 years old (I could be wrong since my understanding of audio gear is very limited).
Any suggestions will be appreciated.
