    Hello
    I currently own an old Sony DAV S550, however i want to upgrade it as it's just an old Home theater system when all i use it for is music. I've recently picked up some Wharfedale Programme 30D.6 Speakers which are in amazing condition. I've heard from a few people that these speakers were amazing and still are.
    However i just need to find an amp that is able to power them, they will be connected to my PC 100% of the time for Spotify usage. Can anyone recommend me an amp that will be good at driving these speakers under around £50?
    Thanks if anyone can help
    (I have hardly no knowledge in Sound systems)

    If this is all working (check for crackles when you move the controls, common fault) it is a bit of a steal.

    Arcam alpha 8 £50 in reading - if all working this will withstand a couple of speaker upgrades in the future.
    Facebook Marketplace: Arcam alpha 8 amp – Books, films & music – Reading, England

    His are you going to connect your pc. With second hand older a,ps you will need to use the line out from the sound card/motherboard and a 3.5mm to stereo rca cable (couple of £ from amazon). Later you can update to a usb dac which will improve sound quite a bit.

    £50 is not much for a hi-fi amp, even second hand.
    I would look at a second hand amp from the like of Denon, Sony, Yamaha, Cambridge Audio.
    You may find bigger bargains if you look at vintage AV amps, before HDMI. For example the Marantz SR-4200. Lots of analogue and dugital inputs, remote, strong power supply, well built and good for music.
    Best of luck.

    Have you tried them with the Sony?. Although this is sold as a home cinema system, it can be used with just the two speakers. The speakers are probably 8ohm models and the DA will have 4ohm outputs, which means no problems but they will not be excessively loud. .

    For the age of amp you’ll get for £50, I’d personally go for a Rotel or a Yamaha; they’re usually built like tanks

    My parents have an 80s AKAI system in the loft apparently which hopefully will be a killer to the S550. I'll update on it this weekend if we can find it in the loft.

    Sorry to be a downer dude, but... the Akai is likely to be on a par with the Sony.

    An 80s stack system is not going to be renowned for its clout or musical ability.

    Aha... I notice your splendid and enviable lack of years sir, and, I therefore assume, alas, lack of cash.

    In that case then the Akai will have to be sufficient for the now.

    But your speakers are fine little beasties based, as they are, on the Diamond series, but built for pro use. So if you can save up the 50 quid, or do a job for it, then the Wharfedales will thank you for it.

    Best of luck :thumbsup:

    Ordinarily I’d agree sir, but (assuming I remember correctly) those particular Sony’s were based around a now medieval digital amplifier design which was particularly feeble and quite noisy.

    I've got a Cambridge Audio Topaz AM1 sat at my dad's place unused.

    No idea if it'll be an upgrade on what you have but, for reference, it did power my Wharfedale 9.1 speakers just fine.

    I’m probably wrong then. It is about twenty years since I heard one. (It was a DAV S300 too, which was the tiniest entry level thing I think).

    The friend who owned it was quite happy with it until he swapped it out for a a Kef 5.1 and a Denon receiver package from RS.

    These amplifiers are probably the closest to perfection of all the items in the domestic Hi Fi setup. 1% distortion is not wonderful, but compared to the Loudspeakers 10%? and maybe the compression in audio, nit so bad. Of course the bigger AVRs are better and have less distortion etc, but compared to the loudspeakers, and their very thin wires, .
    Just saying that even the Da260 type is ok if the speakers are better.

    Have a look at the Forum Rules and Terms, especially about buying and selling before you take this any further. You need to place an ad in the classified section and then link it to this thread.

    I can't apply a different rule to you as a new member but enforce it with established members. The Forum is a very good and safe way to both buy and sell kit but you can't circumvent the rules put there to safeguard members.

    Sorry if you feel offended, no need to shoot the messenger.;)

    I find that curious. I would have thought that the bigger, more demanding the speaker, the more difficult it would be for the Sony to handle the load.

    I am alas not at all trained in electronics and I know you are.

    The Sony DAVs I heard though have all been with their original speakers, and the reason I mentioned the poor performance, as I heard it, was because at the time my friend had the s300 I would go home and listen to my B&W 601s with an old Nad amp (a Power Envelope version, but I can’t recall the number) and obviously it wiped out the Sony for music.

    However, giving it some thought, its hardly a fair or even reasonable comparison.

    My bad.

    So i went in the loft and i found a Pioneer SA-570 Amp from around 1986, it's really good and i found speakers up there but they're pretty much blown and destroyed. Can anyone recommend me with what speakers that amp will power?
    Specifications
    Power output: 30 watts per channel into 8Ω (stereo)

    Frequency response: 20Hz to 70kHz
    Total harmonic distortion: 0.5%
    Input sensitivity: 2.5mV (MM), 150mV (line)
    Signal to noise ratio: 72dB (MM), 98dB (line)
    Output: 150mV (line)
    Speaker load impedance: 6Ω to 16Ω
    Dimensions: 420 x 98 x 223mm
    Weight: 4kg
    Year: 1986
    Cheers if anyone can help with it, thanks

    That’ll drive your speakers quite happily.

    It’s certainly getting on a bit, but if the capacitors and what not are still ok then it’ll do a good job until you can get, say £80 to £100 together for a more modern amp a bit of a newer one.

    I might be tempted to remove the top and, very gently indeed, brush all of the dust out just to stop any possible excess heat build up.

    Good luck.

    My first amplifier (back in 1988) was a Pioneer A223 which also had 30W output. I paired them with Mordaunt Short MS10 speakers and I was very happy with the sound. Found a good pair on eBay in your budget.

    So that Pioneer will drive the speakers? I tried it with the big sh*tty box speakers it had but it was playing very loudly (The audio was distorted but I'm not sure if that was to do with the box speakers which are in fairly bad condition) and i only had the volume switch thingy at about 1cm up. Is that normal ? I read on the manual to use the loudness switch when listening at low volumes...

    Make sure you don’t have your laptop, or any source, plugged into the phono input.

    Use the tuner and tape inputs instead.

    The loudness button is used to increase the low bass and high treble at low volume as these frequencies are not as easily discernible to a human ear when quiet.

    Oh is the phono input the reason it was playing so loudly and distorted? I had a CD player from 1986 hooked up. The CD player was fine as i tested it with my S550 before, is there something different about the phono input to the Tape and Tuner?

    God yes!!!

    The phono input is a turntable input with a minuscule voltage requirement, measured in fractions of millivolts.

    The CD player will lob out 2000 millivolts.

    The Pioneers tuner and tape inputs are 150mv so a CD players 2V will still overdrive them, but it won’t fry them.

    However, the distortion might be because the caps are shot and the bias adjustment is all over the place.

    The best way to test it is to play music through your lap top at 50% (into the tuner input) with volume on the pc slider.

    Then see how it sounds into the Wharfedales. You might get lucky.
