I wanted to give more information regarding the equiment I have. My speakers are nice old JVC's. They are 92db eff W . M . The crossover is 550 hz , 4200 Hz. The speakers are rated at 6 ohm impedence. When I look at a chart supplied to me through the manual it shows the impedence. The impedence goes up to 24 ohm in 30hz to 60hz range and after that it is almost completely flat never going below 6 ohm. I heard that flat impedences are good with tubes. The room I have all of this is really small. Now for my other equipment. After checking other peoples post about the same integrated that I have. My amplifier has a pair of subwoofer outs. From what I read it is a "Sub/Line out" and "line-integrated amplifier" . So if it is true that it has a "line out" what can the amplifier be used for? As for getting the music loud. I dont have the music going loud loud but at a reasonable listening volume and this is with 5 watts; So I dont believe it is clipping or compressing. If I run two 45 monoblocks at a combined 4 watts and combine it with a active preamp the power would be similar to the 5 watts have now so I should be able to listen to it happily right?

  Well, if you read the first page of the DRD offerings, you can expect 1.8 watts per side (mono block). So, that does not add up to almost 4 watts, it's only 1.8. If what you have is rated at 5 watts now, that would mean 5 watts per channel. So you need to compare 5 to 1.8. There will be a difference, though much of that may be based on the tubes and topology of the design. 1.8 can make music with your speakers, but it will be straining.

  As for the line out, that would usually mean that you can bypass the amplifier part of the integrated and use the preamp version with other amps. seems simple enough anyway.

  If you're willing to use the 45s as they are and consider horns or something super efficient down the road, then go for it. It's usually recommended that 45s are used with a speaker at least 104 spl.

    I have 45 and 300B amps driving 98-99 db speakers. Both sound great.

    The 300B is probably the best choice with your current speakers.

    Thanks. I didnt know how the power of monoblocks were determined. I guess I will have to think about the other aspects of my system before I go for something too unique.
