MC Phono preamp gains

Well, which would be better. One phono preamp with three inputs or three separate phono preamps, if the price is the same.
If you go for three preamps, would you go for the same model for all three or different ones?
How about additional cables? How about space?
If Rhea costs $4000, would a phono preamp at 1/3 of Rhea be as good as Rhea?
Well, for me, it seems to be more complicated and less attractive if I go for three phono preamps. If I have three different phono preamps, I may end up using only one that I would like most, and then I need to change cables each time I try different turntables.
There are two used Rheas for sale now ($2400 and $2900), and they are out of my reach, but I will seriously consider it for my next phono preamp.

Many thanks for all replies.

If and when you consider the Rhea, a point to keep in mind is that its highish and frequency-dependent output impedance would be non-optimal if the input impedance of your line-stage is less than around 30K balanced and perhaps 20K or so unbalanced. See the second paragraph here. Also, if unbalanced interconnections to the line stage are used, and if the length of those cables is particularly long (e.g. 15 or 20 feet or so), it would be best to choose cables having low capacitance per unit length (e.g., less than say 25 pf/foot).

Ihcho, if you're looking for MM premps (and you need 3 of them or one with 3 imput) why no try 3 different things with your cartridges and keep the best. So many MM preamps available, if you will search audiogon for preamp thread you will see at least 5 decent options to buy and they are not expensive.

Chakster,
I ended up having two turntables. One turntable has two arms. I use one arm for mono, and the the two for stereos. Some of my LPs are not in pristine condition, but I still listen to them. So I use more expensive cartridges (Ortofon SPUs) for mint LPs and use less expensive cartridges (Denon, Audio Technica, ...) for non-mint LPs.
I currently have two phono stages for three arms, so I need to change cables from time to time.
I am thinking of selling them and buying one that has two/three inputs. Or, I can keep the other two and buy a decent phono that supports one input.
I didn't know about Rhea, and it appears to work well with my setup. The only problem is, I don't have enough budge for it, and I need to sell the other two afford it.

You can use one tonearm for VG vinyl, next one for VG+ and third for Mint- to be correct with your grading (just kidding).
