which AV receiver

[gareth170]

Pioneer VSX330 or DENON AVRX520BT.

i'm thinking about getting the DENON AVRX520BT because it as 2 subs out, 2 Optical Outputs, Bluetooth

but the Pioneer VSX330 looks good because it's 105w per channel. but only a 1 sub out, 1 Optical Output

i think the Denon amp is 6-16 Ohms also.. looking on the back.

i can only spend £230

 

[gareth170]

just ordered the DENON AVRX520BT

i asked a guy at Richer Sounds if my 4-8 Ohms speakers work on it without overheating the amp and he said yes they'll be fine because the speaker can handle anything between 4-8 Ohms so it'll run at the amp spec 6 Ohms minimum. but I'm not sure if thats true what he's sayng. so i may just use my 8 Ohms speakers..

Those power ratings are inflated. That Pioneer is 105W into 6 ohm, 1 channel driven, 1khz 1% THD. That is lousy. You'll find real power output to be no greater than 33W per channel, all channels driven- if you're lucky.

The Denon fairs better Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive) 90 W. In real use, it will be around 66W per channel all channels driven.

FYI the amps I use are 200W per channel, all channels driven, full range 20hz-20khz, 0.03% THD, with SNR of 120dB

the demon amp manuel says this,

Output Power (8 ohms, 20 Hz - 20 kHz, 0.08% to THD, 2-channel operation) 70 W
Output Power (6 ohms, 1 kHz, 0.7% THD, 2-channel operation) 90 W
Output Power (6 ohms, 1 kHz, 1% THD, 1-channel operation) 130 W
Output Power (6 ohms, 1 kHz, 10% THD, 1-channel operation) 140 W

i'll be running 8 ohms speakers so it'll 70w

I think it's a good choice, especially if it's got the features you need.

You have more than one set then if you have 4 and 8 Ohm speakers?

If you use 4 Ohm speakers, then although it does say 6-16 Ohm on the receiver, it should power them fine as long as you don't over stress the receiver by turning the volume up too much. As long as you don't have the volume so loud you hit distortion, you should be OK.

i have 1 pair of speakers at say 4-8 ohms which i wanted to use for the front speakers but if 4-8 ohms means they 4 ohms then i won't use them, but going by the guy, 4-8 ohms means the speaker can be ran at anything between 4-8 ohms

i have another 2 pair of speakers + center speaker that are all 8 ohms

But that's for 2 speakers. It's a av amplifier, not a stereo amp, so you'll be powering several speakers as once. 70W is a plenty for 2 channel and that rating is good, low THD, full range but you have three more speakers, so you'll find it's less than 70W with all channels driven.

Front:



70 W + 70 W (8 Ω/ohms, 20 Hz – 20 kHz with 0.08 % T.H.D.)



90 W + 90 W (6 Ω/ohms, 1 kHz with 0.7 % T.H.D.)



Cen*ter:



70 W (8 Ω/ohms, 20 Hz – 20 kHz with 0.08 % T.H.D.)



90 W (6 Ω/ohms, 1 kHz with 0.7 % T.H.D.)



Sur*round:



70 W + 70 W (8 Ω/ohms, 20 Hz – 20 kHz with 0.08 % T.H.D.)



90 W + 90 W (6 Ω/ohms, 1 kHz with 0.7 % T.H.D.)



Out*put con*nec*tors:


6 – 16 Ω/ohms

does this mean theres 5 separate amps?

 

[gareth170]

ok. well i'll test it when i receive it tomorrow, if it's crap, i'll send it back.

The real question is does it matter? If you've got a half decent set of sensitive speakers, then it might not. If your surrounds are satellites and not full range floor standards then again, it might not matter, since the major of energy used is used to produce the bass notes and not the mid/upper end of the spectrum.

What amp are you using now? This will give you a good gauge on whether the denon will have enough power or not.

at the moment I'm using a samsung ht-f4500 home cinema system (it's not a AV amp as such, but I've got everything playing though it.) due my old cheap amp dead a year a go.. but tbh the sound from the ht-f4500 is really good which surprised me.

do you think the DENON AVRX520BT be better than the samsung ht-f4500 home cinema system?

anyway i have 5 satellites speakers at are 8ohms that I'm planning to use.. i also have bk subs

 

[gareth170]

You've said the set of satellite speakers you have are 8 Ohm, so I assume they are not the ones that came with the Samsung system?

It'll be far better than the home cinema system, but like Marsman has mentioned, please do not even attempt to use the Samsung's speakers with it, somethings likely to go pop rather quickly.

no i know the samsung speakers are 3 ohms, . i have other satellite speakers that are 8 Ohms
