The black Phonos RIAA Phono Preamplifier from SPL is designed for use with record players using either MM (moving magnet) or MC (moving coil) cartridges. The equalization curve is according to RIAA and suitable for all vinyl records. It offers up to 71.5 dB gain for MC cartridges and 50 dB gain for MM cartridges.

The preamplifier uses proprietary VOLTAiR technology (120V rail technology) to offer a high voltage of 120V (+/-60 VDC). The 120V electronics operate quasi 'idle' even at highest audio levels and impulse peaks. They never operate on the limit and therefore never get stressed. The music presents itself with a pleasant serenity and realness.

The purpose of the RIAA equalization, which is a form of pre-emphasis on recording and de-emphasis on playback, is to permit greater recording times by decreasing the mean width of each groove, to improve sound quality, and to reduce the groove damage that would otherwise arise during playback.

Nice shirt but to shiny for the office
Size: X-Large, Color: Blue
I really like the semi professional, clean, well groomed look of collar-less shirts for my semi formal office. It is appropriate for almost any office occasion. Whether we're getting a visit from the corporate execs., or going out for happy hour...I don't feel over dressed or under dressed. However, for this item: Pros: 1. Excellent classic fit 2. Good stitching and well made Con: It is to shiny! I truly want to purchase every color they have in their lineup, but because of the shimmer, this is probably for someone that wants a night on the town vs a corporate office setting.

Good quality
Size: Medium, Color: Black
I purchased two shirts for my husband and they were a perfect fit. The quality of the material was excellent. They recommend dry cleaning and I took them to the cleaners because they were wrinkled with the folds. We will have to wait until he wears one to comment further.

Great Quality
Color: Black, Size: Small
My son loves these shirts. We have them in several colors. They are so soft, light weight and wash great. He is in college and he can throw them in the washer and dryer and not have to dry clean them which is a plus for him. They are slim fit and hold up well. One he has had for 2 years and it still looks great. Great value for the money.
