I just picked up a Pioneer VSX-21TXH for a very good price open box at my local Best Buy, and have a few questions. I've asked these on avsforum, but wanted to ask here as well since this model has been discussed here before.
1 - I've noticed that I need to crank the receiver to about -25db before I get any decent volume out of it. I realize that this is an arbitrary number and is going to vary with speakers of different efficiency, but am wanting to know if this is generally in the ballpark. It seems a little high to me given my experience with other receivers, but wanted to see what you guys generally listen at.
2 - It looks like I can bi-amp with the other set of outputs. I don't need an explanation of bi-amping, what I'm really looking for is some practical experience any of you have with this receiver. Doe you guys notice any benefit? In theory it sounds good because you're using an extra set of outputs, but ultimately you're using the same power supply, and I would think the power supply is going to be the bottleneck, so does swapping power from one set of outputs to another really help? The only way I'd see it helping is if the amp section is a truly discrete design with each channel being completely independent of the others AND the power supply is enough to drive all the channel simultaneously, which I seriously doubt. Ultimately it sounds like with bi-amping you're just robbing from Peter to pay Paul.
3 - I noticed this receiver is only rated down to 6 ohms, what are your thoughts on this thing being able to power a set of Polk LSi7 and an LSiC up front? If I did it and it 'failed', would it more likely damage the speakers or the receiver, or both?
4 - This is more of a question related to Best Buy. Since this was an open box, I went against my tradition and paid $50 for a 5 year protection plan from Best Buy. It's the usual deal, if it gets damaged I bring it in and if they can't fix it they give me a new one. The question I have is what are they going to use as a guage to determine what to replace it with if it can't be fixed, the actual model itself or the price I paid? I paid less than half of retail, so if they use the price I'm gonna be screwed really, but if they use the model number I'd be fine, curious if any of you guys know about this.
TIA for any help.
