Audio Technica AT-HS10 and Ortofon LH 2000 Turntable Headshells premium
Phono cartridges can make or break a turntable, but the headshell also has a not inconsiderable influence on the sound.

R.T.F.S. Ceiling Vane and Carreau premium
In this review, I will try the Ceiling Vanes in three different positions in two areas while applying the Carreau panel in a third area. If there's one thing that has become clear during my time with various R.T.F.S. products, it's that they have proven to be extremely effective. More effective than other foam or wool solutions that I have tried.

R.T.F.S. SiRRAH – Part 1 premium
The smartly designed SiRRAH units have a twofold function, combining the advantages of a diffuser with those of a bass/midrange absorber. The panels are easy to fix to the wall and the improvements are substantial.

R.T.F.S. Sirrah – Part 2 premium
Not only will they work wonders in untreated rooms, but the SiRRAHs also provide substantial improvements in soundstaging, clarity and focus even in already well-balanced rooms.

R.T.F.S. Stripe premium
The Stripe is made from the same material as the Carreau but the added benefit of the Stripe segments is that they provide precise control over the exact balance between reflection and absorption while also enabling precise tuning of the bass behavior.

Shakti Electromagnetic Stabilizer aka Shakti Stone premium
When you think about it logically, its working cannot be explained. The effect is however too big to be discarded, I would argue that everybody can hear it. Mysterious? You bet.
