Why is the trend to make separate phono stage


Why is the trend to make a separate phono stage. Say a high end pre-amp such as Audio Research Reference 2 you need to spend $ 10,000 for a line stage and another $ 7,000 for the reference phono stage. Almost every manufacturer has started to separate the two components. Is this to make more money selling two boxes or has technology gotten so sophisticated that it needs to be separate or lastly maybe only 25 % or less of the buyers want phono, so the manufacturer focuses on the 75 % population that need a line pre-amp. For us oldies it used to be easy to add a MC/MM board to the pre-amp to add the phone section. What happened??

Dcaudio-
I am looking at replacing my current pre-amp (phono & line)for the next ten years
I've been in the same boat. Maybe a solution is, phono + volume control for the rest??? I.e. are you sure the active line's extra db are absolutely necessary??? In a similar vein, some "sota" pres such as Blowtorch mentioned above, provide 6-8 (?) db signal amplification... it's not as if their designers skimp on the issue, surely:)

OTOH as to phono being difficult: While load issues at the phono equalising stage & the various amplification stages *are* tricky, the actual riaa curve is not that difficult to implement (and I'm no "seasoned" diyer, either etc). Rather, it's an expensive undertaking. LCR phonos are very nice -- but finding the right values (think: coils, for example) & matching the components (otherwise, there goes your riaa curve) is beastly. But it's doable -- at a price! Look at the wavac, vendetta, aesthetix, etc riaa's: expensive, but probably good enough to keep one happy 10+ years!

On subject and IMO, it has been said before: there is a MARKET for separates; why not tap it??? I.e. there are TWO products to sell, where before there was only one. Unfortunately, there are also two cases ($$$) two PS instead of one beafed up one ($$), etc. And the cable people make a little extra. I'm not ranting, there are people who don't use phono hence don't want to pay for the extra circuitry. So, pro & con arguments abound!
