The distortion spec is poor at 0.2%
Why not just use a PC, perhaps with an external sound card?
It depends what you are doing.
If you want to make distortion measurements you need an ultra low distortion audio sig gen or a distortion measurement set, such as an HP8903A, which includes a suitable sig gen. Ultra low distortion sig gens and distortion analysers have different specifications, and you pay more for better.
If you want Bode plots a modern DDS AWG would be fine because distortion isn't that important. Once again, you pay more for better.
If you just want signal tracing for fault finding, just about anything will do.
Look into using a PC with a sound card.
I like my connectors on the front not on de side.
so you can stack your measurement devices nicely.
I use a JDS6600. I think it's great.

OP did not tell the details of what audio gear, so assuming noise, distortion, frequency response across 10Hz to 100KHz, possibly including mics and speakers too, so here is a possibly credible testing guide by Ti:
https://www.ti.com/lit/an/slaa641/slaa641.pdfThis level of testing usually calls for external 24 bit audio interface for a PC/Mac and a an analysis software, like REW. 14bit resolution in generators and scopes will not cut it for noise or distortion measurement. It will only cut it to verify it works and equipment does not clip in its operating range.
So if you are selling audio on eBay you can state it tested and works, but not meeting audiophile requirements.
A Focusrite Scarlet 24bit 196kHz sample rate USB audio interface is in the same price range as the Chinese waveform generators ($200) and can do audiophile measurements both as generating and measuring.
Most low /medium cost DDS generators will have 0.5-3% THD at audio frequencies. Thats DDS for you!
So for general testing a cheap(ish), say $300 unit would do. So take your pick.
You could DIY a spot source for a small set of fixed freqs for a few $;

At the lower end of the premium quality range the Keysisght FG33530 is a great buy.
Always check the preloved market before buying new.
I have a BK precision 4052 that I snapped up on ebay for $250!
The Leader units of yesteryear always got positive reviews, but they go fast on evilbay, and often in need of repair.
The siglent SDG 1032x looks like it pairs nicely with a siglent scope, which I'll be in the market for in about 6mo. I'm looking at the Uni-T 932e, .
looks like the uni T is about half the price of the unit you really want ,so why make it more expensive by buying a lesser device first,stash the cash and make do with your pc/phone until you can afford wot you really want
