ModWright PH 9.0 Tube Phono Stage
ModWright PH 9.0 Tube Phono Stage
The PH 9.0 began with a question: how much of the Reference PH 150 could be delivered in a smaller, more accessible package? The answer turned out to be most of it — the Lundahl MC step-up transformers, the front-panel loading and gain controls, the external power supply, and the tube-based gain stage, all retained in the PH 9.0.
Three Versions
The PH 9.0 is the base model. The PH 9.0X and PH 9.0XT represent successive upgrades in the power supply design and component selection. Dan Wright's approach to the upgrade versions is consistent with his overall design philosophy: the foundational circuit is correct from the start; additional investment goes into the power supply and components that allow that circuit to perform at a higher level.
The Lundahl Transformers
Lundahl MC step-up transformers at the moving coil input — the same Swedish-made transformers used in the Reference PH 150 and found in some of the most respected phono stages in the industry. Transformer-coupled MC input provides the gain needed for low-output cartridges without adding the noise that active gain stages introduce at this point in the signal path.
Front-Panel Controls
Gain and loading adjustable from the front panel — no opening the unit, no DIP switches, no guessing. This is how a serious phono stage should work. Try different loading values in real-time and hear the difference your cartridge makes to the loading choice.
Press Recognition
ModWright has been reviewed by The Absolute Sound, Stereophile, and Hi-Fi+. The PH 9.0 has been covered as an exceptional value in tube phono design, with the Lundahl transformers specifically cited as defining the product's character.
