Looking for input on Polk Monitor 35B or Pioneer Pioneer SP-BS22-LR bookshelf speakers . The Pioneer are $125 for the pair and the Polk's are about $150. Are the Polk's worth the extra $25 . Looking for something acceptable punch on the low end and very clear on the upper end. These will be behind a Sony stereo receiver that puts out about 100 watts per channel. I have Polk monitor 75t's on my main stereo which I really like. Have heard generally good reviews on the Andrew Jones speaker line.
