Hi Corey, Feedback-based RIAA EQ is not necessarily a bad thing, if it's done properly. While I have a preference for passive RIAA EQ, or a hybrid of passive for the bass portion and active for the treble, there have been any number of very good RIAA preamps designed with feedback RIAA EQ. I've designed a few myself. But, you won't get one that's been designed properly, with high-performance op-amps, for $25 on eBay. If you're looking for an inexpensive phono preamp, beware of cheap Chinese knock-off ICs. The ubiquitous 5532 dual op-amp is still incredibly popular in even moderately priced phono preamps because it offers very low noise for very little money. While it's over 45 years old and not my favorite device, quality varies considerably from one IC manufacturer to the next. If you get a phono preamp with 5532 op-amps, be on the safe side and look for NJR or TI devices. If it looks like a Chinese knock-off, avoid it. If you get a preamp from a reputable audio equipment manufacturer, you'll probably be safe. Audio Advisor has a wide selection of phono preamps in varying price ranges, including a few from Pro-Ject and Music Hall for around $60 (www.audioadvisor.com). But, any preamp on the low end of the price scale, even purchased from a reputable dealer like Audio Advisor, will necessarily offer performance that's compromised in one way or another. But, related to what I wrote earlier, we have every right to expect that even a lower-end preamp will be free of hum. If you buy something from Audio Advisor, they will allow you to return it if you're not happy. Regarding Steve Smolian's comment about cheap phono preamps not having RIAA EQ, I wonder if he can cite any specific models. The only phono preamps I know of that do not have RIAA EQ are those specifically marketed for flat, archival transfers. Diamond Cut Productions sells one of these (www.diamondcut.com). An LP record played on a flat preamp will be difficult to listen to, with screechy treble and no bass.

Do not open attachments, click on links, or provide your credentials if the source is suspicious. Good advice! I shy away from the cheapies because they use 'jelly bean' IC's, and they typically have the equalization in the feedback loop of the IC. Both are a bad idea when it comes to audio fidelity. You get what you pay for!
