Would I be better off with some active speakers?
Thanks! How would I connect passive speakers that have two (black + Red) connectors on each speaker?
The Syba sonic, is a headphone amp not a speaker amp. Hardyxd got a bit mixed up. Possibly missed the part where you mentioned about speakers.
SMSL SA36 or 50, maj mentioned, is a good choice for cheap small speaker amp.
There are some decent active speakers to be had, such as those from Edifier, if you'd prefer to go that route. They are very good, but one advantage to buying passive speakers and an amp, is that you can get many passive speakers that cost less than they used to. Active speakers don't drop in price the same way.
Also passive speakers are more solid in terms of reliability. As they have no amp inside, they have less electronics. Electronics will be the thing that go in active speakers, if there is an issue. With cheaper active speakers, more corners are cut to meet a price point. Very often that is that power supply. If it ever comes to it; cheaper to replace the amp, than the speakers.
Depending on what size of speaker you want and how much you want to spend, Wharfedale Diamond 9.0 are great speakers for around £50 from Richer Sounds.
Could I use these : https://www.amazon.co.uk/AmazonBasics-Speaker-Cable-Gold-Plated-Banana/dp/B07FKJDTPY/ref=sr_1_9?dchild=1&keywords=speaker+cable&qid=1587397604&sr=8-9&th=1
instead of bare speaker wire?
Glad to help. I use a similar set up myself. I have a Topping TP21 amp and Roth Oli speakers. They are the same size as the Wharfedale's and for my desk, just right. Anything larger would be too big!
Did you go for desk speaker stands or floor standing ones?
Just curious, as some people do use desk stands to raise the speakers so the tweeter is ear height, and to help decouple the speakers from the desk to stop unwanted vibrations.
One more thing, do you turn your AMP off after use? Or just minimize the volume?
I only ask as I heard its better to leave the AMP on to aviod "warm-up" or such? Is that true?
I put my amp's into standby mode, or at least soft off. The reason is it's kinder to electronics as it reduces the repeated surge of main power off/on over time.
Regarding warm up, yes you can get a change in sound, normally amps sound better after 20mins or so off use. You'll be hard pressed to notice the warm up on a modern class B amplifier, however I still believe it's there.
The issue with many small PC speakers is either the speaker driver/woofers used are too small, or the cabinet/enclosure is too small. You don't get much body to the sound then, hence why many come with a subwoofer to make up for the lack of lower frequencies. Having 2.1 brings it's own problems though, in that there is a disconnection between the small satellite speakers and subwoofer, when it comes to the sound; as if there is a hole or something missing.
I went for this AMP - https://www.amazon.co.uk/gp/product/B00SATAEEA/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
So im guessing I cant "standby mode" or "soft off" no?
