Hello
First time posting, long time following and learning from everyone's experience. Though I just noticed all the good reviews when I did a search came from ASR. Kudos!
I have a Denon AVC-X3800H powering 9 speakers and processing 11 channels in a 7.1.4 setup. My LCR are powered currently by Emotiva Basx-A3. I am located in Egypt and products are VERY limited over here. My floor level speakers are all Polk Audio Reserve series. R700s, R400, R100s and heights are RCi80.
My question is, I read Amir's review about the X3800H and I understand that the pre-outs deliver around 1.4V. I am considering an upgrade for my frontstage through 1 Stereo and 1 monoblock (maybe start with just the stereo). The vendor that meets my travel pattern is Audiophonics. Based on many threads on ASR I get that there is basically no audible difference between these amplifiers Purifi,NcoreX,Nilai (at the same level/variables). Now since I am bound by the low preout voltage on the Denon. Would it be best to go with 1ET6525SA with around 25db gain to get full power AND better signal quality? Or NCX500 at 31db buffer?
I noticed in Amir's review of the Apollon implementation of NCX500 that using the buffer reduces SINAD slightly. Would this mean that I should always opt for amplifiers with lower buffers that match the preamp's output voltage (assuming both amps are of similar quality like these 2).
They offer HPA-S600NCX (NCx500 modules) which offer these gain settings: I figured I should be around 31db to get full power.
Bypass : 11.5dB
19dB
25dB
31dB
33dB
They also offer HPA-S450ET (1ET6525SA) which offer (in RCA):
12.5dB / 5.03Vrms
20dB / 2.12Vrms
25dB / 1.24Vrms
29dB / 0.75Vrms
