Total System Gain Question
@cleeds There's no way to calculate power output in watts from the information the OP has provided. You simply don't know what you're talking about.I'm going to dip out after this. If you know the gain and the input voltage, you know the output vo... 
Total System Gain Question
You’ve confused gain (and input sensitivity) with power output. They are two completely different things. There’s no way to calculate power output in watts from the information the OP has provided.Input sensitivity, gain and power output are all r... 
Total System Gain Question
That’s a lot of gain, works out to around 2500W into 8Ω at full volume. A rule of thumb is that every 6dB of gain doubles the voltage, if you know Ohm’s law you can work out the rest.If you ran a unity gain (0dB) preamp into that power amp it’d ne... 
RCA to RCA versus RCA to XLR
I think shielding like most things is down to circumstances, I've got wifi with around 30 devices attached (god knows what they all are). So I can't do without it, the only issue I've had is TT interconnects as the capacitance adds to the cart loa... 
Lay Off the Newbies!
Ahh... okay, got you. 
RCA to RCA versus RCA to XLR
@oldhvymec is there a bit of "different" thinking going on.Yep, there's always more than one way to skin a cat... I was just addressing the comments saying there there was no benefit going RCA to XLR. If you have no issues with RF, ground noise et...

@georgehifiThere are no stupid grandiose claims about thingsWho are you quoting there?.. the other two are mine but I can't find that on the page. 
RCA to RCA versus RCA to XLR
I try to explain thing simply.Thanks for the simple explanation, I'll try to explain as simply as I can why you are not correct. If you connect ground to pin 3 then it will be inverted at the input and there will be some benefit of the balanced co... 
Lay Off the Newbies!
I think the biggest barrier to educating yourself is being afraid to ask a stupid question. There are no stupid questions but there are plenty of off-topic, self aggrandising answers. My advice to any newbie would be don't be afraid to ask the que... 
RCA to RCA versus RCA to XLR
Without seeing the preamp schematic I can't say for sure but it is likely you'd get an improvement in ground noise rejection as long as ground is connected to only the cold wire (XLR pin 3) at the RCA end. This may come at the cost of increased th... 
Looking for a 2-channel high end volume control
Optical resistorhttps://tortugaaudio.com/products/diy-preamp-components/electronic-stepped-attenuator-epot-v3-max/Haven't come across talk of LDR attenuators for a while... I could never work out what the attraction was. This one tracks about the ... 
A full range speaker?
@ggc I mean this sincerely, thanks for posting those links. I’ll have a good read with and try to keep an open mind. 
Looking for a 2-channel high end volume control
Interesting to learn about the Muses, I've not come across that manufacturer before. Spec is very similar to the Cirrus and TI although the Muses has a gain stage built in (but not great distortion figures).In all honesty I'm not even sure whether... 
A full range speaker?
@mozartfanNot saying I believe it... I'm interested to know where the information is published. BTW you need to consider the audible harmonics so if you rolled off at 2k it wouldn't sound so great... I'm sure you know that but thought I'd just be ... 
A full range speaker?
The entire audible environment for Humans measure at 15Hz - 150kHz.Where do you guys get your information from?
