hi, yes. i would appreciate your help if you like to share your experience with your new 1.3 Extreme. What are the new improvements that you notice? how long have you been burning in this new preamp ? Thank you for any info.
The output impedance of Rhumba is a low 75 ohms. Based on what @almarg once told me, this will match with your Bryston 4B3 amp, which has an input impedance of 30k Ohms.
Check this thread:
Bringing this thread to life to find out from current Backert Rhumba users on what is the volume position on the dial that they generally use for listening?
My story is that I used to use it 90% of the time between 9 and 9:30 position and it sounded fine. Very rare SACD recordings used to allow me to bump it to 10 or even 11 o'clock position. But recently came across this thread on Oppo UDP-205 that I use as my DAC. Apparently, setting the volume control setting to "variable" you can go down to 70 (from a max 100 = Fixed), without loosing the resolution. I experimented with the setting and I have set it to 90 now. With this I am able to get anywhere between 12 and 1 o'clock position comfortably. Some SACDs might allow me to go to 2 o'clock position - is my guess.The best part is that, this gives the music more texture and I can hear better nuances. The system sound more natural now and what I used to think as "fine" before, now sounds more strident. Bob in that thread discusses how we do not lose resolution by lowering the output level to a certain point.
TBH, I never used to like the idea of a DAC with "variable" volume control. Suddenly I am ALL for "variable" volume control in a DAC, as long as we do not lose resolution. If at all, with all the "loudness war", we only stand to gain more resolution (not in the recording, but output of playback). Have you all experienced this? I am thrilled to say the least.
