Improved Harmonics, Low Noise, Layered Presentation
New and improved line of preamp for vinyl users, QA Phono Stage is a high-performance bang-for-buck product latest in our inventory.
OEM Modified and Upgraded, we have made critical and significant improvements in our Phono Stage clearly better than stock. The ground was replaced with a gold-plated binding post which now enables a banana plug fitting in addition to just spade in the previous version.
Miflex and Auricap from Audience are chosen for their superb audiophile quality as well as fitting size in film capacitors to upgrade from the existing stocks caps in the circuit. The crispiness of the sound from Miflex and the lush openness of Auricap complimented remarkably well in these pair of upgrades and has more than delivered an exciting output as a result.
The implementation of FETs as opposed to opamps give a very musical and clean sound signature less sensitive to temperature changes affecting the distortion. For some, FETs tend to possess traits of tube in warmth, while still adding on to a livelier presentation, improving the PRaT.
QA Phono Stage further increases in performance on feeding in with linear power supply at 16V 1A.
QA Phono Stage is MM and MC cart usable. The default cartridge loading impedance is 47k ohm for MM and 470 ohm for MC. Figures are customisable according to user preference. Please state the desired ratings on ordering.
