- An even better bottom end foundation to the music
- More body to the performers
- An increase in soundstage depth and front to back layering of the performers within the soundstage
- A greater sense of ease and flow to the music
I went back and forth between these 2 rectifiers a total of 3 times using the same music to verify all of my findings. When I had finished, it was very easy to recognize that the 1945 RCA CRC JAN 5R4GY rectifier provided the superior sound from the Allnic H5000. This somewhat surprised me because of my previous rectifier testing results. I had assumed that the 1940 RCA 5Y3GT would prove to be the better fit for the Allnic H5000.
In comparison between these 2 rectifiers when used in the Allnic H5000 phono preamplifier, the 1945 RCA 5R4GY provides a more refined sound, with greater transparency and better resolution. Voices and instruments just seem to have more texture and nuance with this rectifier providing a better sense of the performance. The soundstage is wider with this rectifier and the space and separation between performers within the soundstage is much better. The overall sound is punchier with the bass power and impact especially better while still remaining balanced within the overall sound.
The 1940 RCA 5Y3GT provides an overall warmer sound, but in doing so it casts a slight veil over the music (losing the wonderful transparency of the 1945 RCA 5R4GY). It also has less bass impact and clarity. The soundstage is not as wide and performers within the soundstage are closer together.
In summary, the sonic improvements that the 1945 RCA CRC JAN 5R4GY rectifiers make in the Allnic H5000 DHT phono preamplifier are very significant and easy to hear in my system.
