Hello, good evening / good day,
Currently I'm using Diablo's 4.4mm line out to XLR input to the drive the RNHP Amp. The SQ is so far so good. But the powerful line out means that I can only use the POT up to around 9 o'clock! As my headphones are mainly relatively high sensitivity ones (~30 to 70 ohms with sensitivities > 100 dB/V SPL). Since the XLR input level of the Amp is +22.8 dBu but the RCA input level is +14.7dBu, I'm thinking that if I use the RCA input instead of the XLR I may be able to use a fuller range of the POT! Then I end up with 2 options:
1) Use the Diablo 6.3 PO to connect to the Amp's RCA input. If done this way then what volume should I use on the Diablo? Like can to turn up the volume all the way up to close the max? Btw the iFi Diablo website states the following max phone output,
BAL
>19.2V/611 mW (@ 600 Ohm)
>12.6V/4,980 mW (@ 32 Ohm)
SE
>9.6V/153 mW (@ 600 Ohm)
>8.8V/2,417 mW (@ 32 Ohm)
So I should get max 8.8 V from the 6.3 PO, right? which is less than 12.6V from the 4.4! Btw, the website doesn't say anything on the 4.4 line out output level! and should I assume its equal to the max bal line out?
2) Alternatively is there such an interconnect that connects a 4.4 line out to a pair of RCA input, without damaging both the Amp and Diablo, and with no adverse effect on SQ?
Hope someone could enlighten me with advices and answers.
TIA ..
