Thanks for the tip about Dolphin; I’ll keep them in mind for future purchases.
In the event, it would have made little difference to the price, as their Euro price today is €94.27 plus €12.29 shipping.
Yes, I can edit the first post.

Greetings
As promised I am posting my experiences using the Edirol UA-5 with Audacity and Windows 64 bit Professional. The great advantage for me was that I could use the sensitivity to lower the incoming signal and so control the distortion I was getting previously using only the internal sound card. The recordings are quite nice and I used LAME when they were done to produce a quite acceptable MP3 file that was a tenth the size of the original .wav. I had to fiddle a bit with the settings. What worked for me was cranking up the volume of the cassette player (my source) and then using the sensitivity setting left and right on the Edirol to control the levels.
Good luck to all.

Review: StarTech ICUSBAUDIO.
http://us.startech.com/product/ICUSBAUDIO-USB-20-to-Audio-Adapter
We use these little machines on all three computer platforms, so it’s pretty universal. Nobody is going to give Technical Academy Awards out, but for headphone monitoring or microphone amplification and conversion, it’s remarkably useful. It’s doing all its tricks with the 5v USB battery, so if you have a noisy or unstable computer, this battery system will be noisy and make your sound noisy, too.
It will supply 5v computer battery to a “computer microphone” to run it. If you don’t need the battery, as I don’t since my microphone has its own battery, the plug just goes around it.
I was using a Radio Shack 33-3013 Tie-Tack microphone, so the entire, single-channel sound system comes in around $49 USD. If your built-in sound card isn’t up to the job or you have a Mac, this will adapt your simple, single microphone for recording.
The first clip is the raw capture. The second clip is gentle noise reduction in Audacity 1.3.12. It could be argued that this system was made for noise reduction. A slightly noisy performance made very nearly perfect.

There is a down side. The microphone system is slightly noisy, although I point out in a separate posting that you could use it as-is if you weren’t too particular (and anybody with a $40 budget can’t be too particular).
The headphone volume is all you can do with a 5V battery – which will not make your ears bleed.
The most serious problem is the creation of a DC offset in the sound. Most of them do it. I happen to own one that doesn’t, but I also have two other ones that do. When you get finished with your recording, you may find that there is a downward going DC level at about -38 dB or so reading from the dB ranges. You can easily get rid of it with the Normalize Too, but if you don’t know to do that, you will have a voice track which will pop or click when you edit.

USB 2-channel audio interface with 24 bit 48 kHz max recording capability that really works nicely both on windows and in Linux without any big troubles or glitches so far. Powered by USB connection.
Inputs:
2 x MIC XLR (with optional +48 V), 2 x Guitar/Line, S/PDIF IN, MIDI IN
Outputs:
MAIN L/R 1/4", Phones 1/4" stereo/mono, S/PDIF OUT, MIDI OUT
Pros:
Robust case, controls and switches feels pretty reliable. Very easy and straightforward to use and Audacity has no problems handling it. It’s possible to mix the monitor feed anywhere between direct and USB sound. It works with Linux!
Cons:
The meter LEDs are not that finely graded so it’s a bit difficult to set the levels exactly. At very high gain levels it of course gets a bit noisy. There’s a tendency to introduce DC offset with the recordings.
Thanks for that review larpal - I have added it to the initial post in this thread.

Should you add StarTech ICUSBAUDIO above to the front page of this thread?
And add (only) ARTCessories USB Phono Plus V.2 to:
Missing features - Audacity Support ?
Thanks
Gale
Done - I editied Koz’ posting into the requesite pro-forma layout.
And done (I used Irish’s summary that he made for the front page of this thread - with some edits).
But why aren’t we adding Koz’ cute little StarTech device to the Wiki too? Is there a reason for excluding it there?
Peter.
In the first post of this thread I also added links to the manufacturers’ websites for each of the devices that are still available - and updated the pro forma with a Manufacturer’s Website: field.
Peter.
Thanks, Peter. I reordered the front page so the devices are in alphabetical order.
Not really except that the description isn’t clear enough because it says it has a headphone input - does it have one headphone out and one mic in so that basically it’s an iMic competitor?
iMic is on the Wiki page already though not on the front page of this thread. Is StarTech recommended above iMic because of less general noise, in spite of the DC offset issue? In the UK you can get iMic as cheaply as StarTech e.g. on Amazon.
Gale
We’re using the StarTech mostly for the audio output – to drive headphones or, in one case a small sound system. Size was an attraction.
The sound system in and out (both line level and stereo) jobs are being taken by the UCA-202. Nobody on the sixth floor could keep the built-in sound cards running reliably in the linux machines. The Behringer works very nicely and even I can install one with my Systems Learner’s Permit.
And yes, the iMic would be something of a direct competitor. Someone needs to see if the iMic has DC offset issues. I never looked because it didn’t last long enough in service because of other issues. Does the iMic still have a Line-Mic switch?
Koz
Good idea - thanks for that
Oops - I just fixed that 
That’s what the specs say on the manufacturer’s website:
"Connector Type(s) 1 - USB A (4 pin) Male
Connector Type(s) 2 - 3.5 mm Mini-Jack (3 Position) Female "
(unlike Koz I’ve never seen one in real life)
Peter
From a Google search, no or slight offset:
Yes. So it has one up on Startech if you have a Mac with no audio in.
@Peter, I added Computer Connection: to the front page pro forma as one device has this in its description and I think it’s less confusing than talking about 3.5 mm and USB inputs and outputs.
Gale
I see from here that my Edirol UA-1EX which I’ve used for years has been superseded by the Roland Duo Capture. I mainly use my device to record radio programmes. I do like good quality sound. Is it worth my spending £60 or so to update. Would you recommend?
I suspect not 
My suspicion is that the DAC chip is likely to be exactly the same - when I wrote abut the superseding it was relating to the current commercial offering from Roland, the way they package the device.
I still run my UA-1EX with excellent results.

Creative Sound Blaster X-Fi HD
External USB sound card, 2 channel stereo
Front panel has a volume control, 1/4" headphone output jack and 1/4" microphone input jack. The volume control has no mechanical limit stops and duplicates the function of the on screen volume sliders.
There is a blue power indicator LED on the top of the case near the front panel.
The rear panel contains a phono ground connector, gold plated RCA Line In/Phono jacks, gold plated RCA Line Out jacks, optical Input and Output connectors and a Mini USB port.
The unit contains a dedicated headphone amplifier and an RIAA equalized phono preamp.
Creative claims a S/N ratio of 114 Db, and reviews I have read indicate the device uses high quality DACs.
I purchased the unit because I wanted What U Hear capabilty, portability, and need only 2 channel stereo. The phono preamp was a welcome bonus that allowed me to retire my old preamp.
I am using the unit with Windows 7 and have not yet tried it with Linux.
I have read that headphone volume is somewhat limited because of the 5 volt USB power, but I have not found this to be an issue with my Sony MDR-V6 headphones. The sound quality of the headphone amplifier is excellent.
One review I read laments the exclusion of an equalizer, but software supplied with my unit includes a ten band equalizer
Thanks, Ken. I added a link to your review on the front page of this topic. So, no real cons with this card in your experience?
Gale
Does the iMic still have a Line-Mic switch?
Yes. So it has one up on Startech if you have a Mac with no audio in.
My recollection of this thing is of a rotten, low gain Mic-In coupled with a high-distortion Line-In that overloads easily. It’s truly a convenient external version of the average laptop PC audio connection.
I was not particularly picky about using it, but I found it’s perfect home in a box in the garage.
Koz
As per the contrary evidence I posted before, not everyone finds that. Experience may vary, perhaps if the USB input is not as “hot” as it might be.
I do have an iMic now but I have not tried it yet.
Gale
In my applications, which so far include only LP recording from a Stanton 881S cartridge and a couple of 78 RPM recordings via What U Hear, I have seen no downside. I doubt that I will ever use the Mic input.
The Phono/Line In switch is software actuated.
This soundcard works like a dream on a fairly “weak” Laptop
Laptop is 1.3ghz 4 meg ram.
OS is Windows 10
Everything works perfectly with no latency.
i have recorded my band bass and drums very successfully last week in the rehearsal studio.
2x mono recordings with bass panned hard right
drums submixed 4 channels to 1 panned hard left
guitar and vocals overdubbed at home - no issues at all
