IMHO, think the Cyrus phono a decent solution.
Although I’ve heard it in the past, haven’t had the chance to compare with other options A/B comparisons.
Looks like @Toon has done that. So, better placed to comment. Judging from comment seems the conclusion was SuperLine offered a gain…
Maybe @Toon can expand on that bit…
In our case…
The start was an idea that our newly refurbished LP12 had more to offer.
A better or best phono might be required.
At the time, we had options to use with internal phono cards in a NAC72, or a separate Rega Aria phono. However, the Rega Aria really needs to go back with a RP6 we have.
Over time, we considered Linn options, as well as Naim and the Rega Phono’s
Using our own LP12 as source, our start point was the Rega Aria, which we use at home.
We auditioned Rega Aria, as a start to the demo’. (As the reference point).
Then SuperLine. Then SuperLine with HCDR. Then Rega Aura.
At that point, backwards and forwards several times between SuperLine + HCDR and Aura.
SL maybe needs an external psu, at least HCDR, to compare with an Aura. (But, guess maybe budget wise, that seems fair and reasonable).
The SuperLine and Aura are both good, but subtly different in presentation.
There are many things the Aura does well.
SuperLine works really well - on its own - with the Naim SuperNAIT 3. (One box solution)
Adding a HCDR improves SQ a little more. (Two box solution)
In the end, we decided to add an external power supply, as our use case envisages using with both SN3 and also NAC72, (which would require the psu).
For clarity, deliberately didn’t add SuperCap to the demo’, (avoidance for obvious reasons)
Only mention this, as obviously can’t now comment on this option. But others have said SL + SC is an entirely impressive combination. So, that’s also another option. (Or at least, maybe in time).
Tony and myself also considered the new New Classic NVC TT with its own NPX TT psu, later, when that appeared too. We felt the SL offered more.
As always, go and listen to the options and develop your own thoughts.
Hope all that helps?
Good luck
