This makes a lot of sense to me. Is it fair to say then that a manufacturer may choose to include a greater amount of capacitance in its design to enable the amp to be used with more difficult to drive speakers (i.e. taxing load/phase angle)? I can see why this would make commercial sense. If so, does it therefore follow that if you're running on AVR capacitors (like me) then it's probably wise to stick to easy to drive speakers?It's not all linear so is hard to say exactly, but more power and specifically amps with more stable current delivery at low ohms = better sound, usually means better PSU and Capacitors as well as highly rated amp modules.
Feature wise maybe, but amplification wise that was a massive step down for you. The 4310 was from Denon's "Battleship AVR" era of 2008-2010 when they had massive PSUs and heatsinks - the thing was beast compared to today's offerings. S&V tested the 4310 at 114W/105W with 5/7 channels driven at 0.1% THD - that's easily up there with the X8500.My AVR (required for 4k) step up was an x3600

My Yamaha RX-V3900 was from the same model year and, being a very similar price, was a direct competitor to the 4310 and is also a fairly meaty build.
Yes, I have a question for you about your new A3.Lol. I’m so lost. Anyone want to chat about Emotiva BasX series. ;-)
I've had some comments but not answers. Frankly I suspect nobody can answer this in an informed way unless they've actually tested various different kit at different listening levels. I'd probably be better off speaking with an experienced dealer on the subject.@Mr Wolf you've pretty much had three answers to your question in post 81. I'd say you need a new thread (and link it) if you want to open up the question to more members.
Thanks @Thatsnotmynaim , my current speakers are all B&W. The system is only used for TV/movies in a dedicated HT room.
The mains are DM603 S3 (impedance/phase plot below). These are a 2.5-way towers with a 6.5" woofer and a 6.5" mid-woofer. 90dB sensitivity. The dedicated LF woofer rolls-off at 150Hz i.e. both woofers are used <150Hz and above that the mid-woofer's on its own.

The centre is a (matching) LCR600 S3 2.5-way which has a 6.5" woofer and 6.5" mid-woofer. 89dB sensitivity. The dedicated LF woofer rolls-off a bit higher at 300Hz.
Surrounds and backs are 685 models which are 6.5" 2-way bookshelves. 88dB sensitivity.
All speakers set to Small and crossed at 80Hz to my new babies, a pair of SVS PB-3000s (800W, 13", ported).
AVR is a Yamaha RX-V3900, 140Wx7, tested at 189W/150W/98W/88W per channel with 1/2/5/7 channels driven into 8-Ohms and at 245W per channel with 2 channels driven into 4-Ohms. Power capacitance of 36,000uF (2 x 18,000uF) and reassuringly weighs in at 17.3KG.
Estimated peak power required/headroom at -15dB listening level.

While this is obviously only an estimate, I have some confidence in these figures as it tallies well with the peak power consumption measured at the wall socket. At that low level of amplifier utilisation, per Audioholics Class A/B is only circa 12-15% energy efficient so 25W/0.15+88W (no signal power consumption) =255W. In most action movies the max. peak power consumption observed is under 190W but I did see it once get to 260W, never higher with movies. When playing around testing, I once got it to 340W with music in 7-channel stereo mode at a listening level well above what I would ever want to use. The AVR's rated max. possible power consumption is 1100W (per manual) and it always runs very cool.
Never tried it with an external PA so can't compare but, to my ears, the system sounds incredibly clean and dynamic so I don't perceive there will be much, if anything, to gain from adding one. That said, I'm also mindful that you "never miss something you never had" so have an open mind on this.
To keep this post relevant to this thread, would you expect a Basx A3 PA to improve this system at all and, if so, to what extent? Based on the above, I would not. An XPA-3 GEN3, possibly.
Not relevant as I'm using no more than 7W per channel!Check pre out voltage on Yamaha they aren't always the best usually 1v.
Hi Mr Wolf,Yes, I have a question for you about your new A3.
I've seen your video review (well done by the way - great production values IMO) and wondered what sort of volume levels you're listening at given you perceive the 7011 has less punch?
Hey mate...To keep this post relevant to this thread, would you expect a Basx A3 PA to improve this system at all and, if so, to what extent? Based on the above, I would not. An XPA-3 GEN3, possibly.
