Looking for A Cost Effective Phono Amp- Any suggestions?"

I noticed your mating with a Linn. I have PS Audio matched with a LInn Lp12 with pink link out board power supply with Soundsmith cartridge. The pink link helps with dynamics. When I sent lp12 in for upgrades I pulled a Linn Axis with basic plus tonearm out of closet to match with ps audio. I always thought Axis was light in presentation but had never plugged it into ps audio. I was a little surprised how much better bass was now mated with the ps audio. From what I understand they are easy to mod and a hifi tuning fuse did help a in my GCPH. Never thought I would use phase switch but I use it all the time.

For excellent sound and highely flexible I'd recommend the Ifi Iphono2 At around $500 or less is quite good for the money I'd put it against many others up to a grand.

Really appreciate all the valuable recommendations. Have anyone used the Music Hall PA 2.2. The comments regarding Linn are quite useful .

Plinius Harrah (used) sounds very good and can handle both MM and a wide variety of MC cartrdges via internal dip switches. 

My two cents........ NAD makes an excellent phono amp. Very reasonably priced and they sound fantastic.
