The Alchemy PPA-2 is a full-featured phono preamp that uses all analog, discrete FET gain, and EQ stages to transform microscopic grooves in vinyl into stunningly lifelike music. The PPA-2 can be tailored to specific cartridge requirements, with switchable gain for each channel, MC cartridge loading, and stereo or mono operation. A selection of RCA or XLR inputs and outputs adds even more flexibility to the most versatile phono preamp in its class.

| Rupert Neve Designs RNHP is a state-of-the-art headphone amplifier. Now when Mr. Neve turns his attention to anything, you know it's going to be good. And spectacularly so. What the RNHP delivers is reliable, reference-grade amplification for any pair of headphones. Based on the headphone amp in the RND 5060 Centerpiece, the dedicated 24-volt design is spec'd with calibrated +4dBu Line, RCA, and 1/8" stereo inputs. Everything's housed in a road-tough, VESA-mountable steel chassis. The unit's effortless sonic performance and the ability to drive virtually any 'phones without compromise let you perform, mix, and savor your music with stunning clarity.

- Unerring accuracy for better performances
- The benefits of near-zero-ohm output impedance
Unerring accuracy for better performances
You know you perform your best when your cans sound great - and that's where the RNHP can make a huge difference. Many integrated headphone amps are plagued with a non-linear frequency response, as well as noise, distortion, and skimpy headroom. To some, these units' lackluster sonic performance may seem "close enough for rock 'n' roll," however at Sweetwater, we believe there is the performer's subconscious response to consider. After all, if you're not inspired by what you're hearing, your performance will suffer.
The benefits of near-zero-ohm output impedance
Rupert Neve Designs spec'd the RNHP with near-zero-ohm output impedance to minimize frequency-based reactive-load impedance shifts - a problem unique to headphone monitoring. This ensures accurate sound reproduction, which is obviously important if you need to trust the decisions you make with headphones. You'll find the RNHP's unerring accuracy beneficial when you're using just one set of cans, and also when you're comparing a mix on multiple pairs of headphones.

NAD has a distinct reputation for creating some of the best performing budget amplifiers of all time. The lineage is impressive, all the way from the 3020 of 1978 to the current C 328, with many “Best Amp” awards and five-star reviews along the way. The C 316BEE lived up to expectations, garnering multiple accolades including an EISA award for ‘Best Product 2008-2009’ and top recommendations from the world’s leading audio publications.
With the resurgence of vinyl, NAD decided to update the design by including its highly acclaimed RIAA phono stage. This sophisticated circuit combines low noise with high overload margins to eliminate noise and distortion. RIAA equalization is extremely accurate (a rarity at this price) and there is even an infrasonic filter to reject airborne vibrations that can cause parasitic feedback.
