the differences are MASSIVE!Really?

While I understand and, to some degree, agree with your point about the price/performance issue regarding the reviewers phono stage, you seem to be glossing over the fact that many pieces of equipment perform well beyond what their price indicates. Perhaps the reviewer has auditioned several phono stages on his own and determined that his $900 performed just as well as a $4000 phono stage despite the MASSIVE price differential? The numbers that follow the "$" do not determine whether a piece of gear is mediocre or not. The sound in your system to your ears does.
Forget about the price of the cartridge. In my opinion the phono stage is THE most important part of the analogue chain. I would be far happier with a $4000 phono stage and a $900 cartridge then the other way around. But mate a $4000 cartridge with that $4000 phono stage and you will see what both are really capable of.
Of course, price is not the sole factor here - just making a point. Better equipment tends to cost more and is generally not fully appreciated until you pair it with equipment up to the same level of merit.
I think I haven't quite put the point across properly.
How can you find out how good the A90 is by playing it into a cheap phono stage. It's a bit like running a Mercedes C63 and using 92RON and cheap tyres. You just won't get the best out of it.
I'm not saying you need to spend $4000 on a phono stage but what I am saying is that to REVIEW a $4000 cartridge through a $900 phono stage is plain wrong - you'll never really know what the cartridge is REALLY like.
Everything that you say/type would be logical and would make perfect sense, such as your Mercedes/tire analogy, if the prices of high-end audio equipment were directionally proportional to their performance but that is just not the case in many instances. Prices for high-end audio equipment have in most cases become rather arbitrary with no correlation to their actual performance or built costs. This is all part of the "Great Audiophile Swindle" that many on this forum have fallen prey to. It was a totally different story in the high-end in the 80's when prices WERE directionally proportional with both performance and built costs for the most part, you always had marketing types like Mark Levinson then for overinflated prices but in general you got what you paid for back then; now that is usually not the case.
You are right, it makes no sense at all. I am using a $8000 + table, a $2200 separate phono stage and I paid no more than $400 of any of the cartridges I use. The Slee is not as good as my back up Dynavector 75 -2. The phono stage is going to limit the performance of the cartridge and if one cartridge is already better than the phono stage then a better one will make no improvement. The system is no better than its weakest link, which in this case is the Slee. When HIFICRITIC tested a group of expensive cartridges they used an Audio Note AN-S4 transformer into 3 different high end phono stages to get a broad view of the performance of the products being tested. This test is entirely useless. The Slee is not bad but its use here is entirely out of place.
What Rob is saying in my book is that the Ortofon A90 is the companies statement product, an all out assault on the SOTA in cartridge design and manufacturing. So he's right that it makes no sense to review it with anything but the best phono stages (for instance ARC, cj, Zanden, BAT, Ayre, Lyra, TW Acoustics, etc.) and to really hear everything this cartridge is capable of doing.
Otherwise, you're just going to hear everything thru the lowest common denominator and are you hearing the cartridge or the phono section? Would you put a SOTA cartridge in an inexpensive tonearm with lots of colorations and then try to ascribe a character to the cartridge? Not likely either.
Fact is, most reviews are worthless except to tell you the features of the product under test. You mention the phono stage, but I also have to wonder about the tonearm and turntable that were used, not to mention the linestage, amps, spkrs, wires, etc. I agree strongly that price is not proportional to quality, but in this case we have some other information to go on re the products in question. What you might take from this particular review is that this reviewer using this particular system cannot hear significant differences between two very expensive cartridges made by the same company. This is not at all surprising.
I only mentioned the phono stage because the reviewer pointed out the A90 sounded 'warmer' through the Slee.
All I am saying is that to hear how good the A90 is, is it not worth putting it with the 'type' of equipment it will be used with? I don't know about you but I heard that the Cambridge audio 640p was a good phono stage...I heard one in my system and it sounded CRAP! Compared to what I was using at the time, the Cambridge sounded.... well crap!
Some folks think the 640p is as good as if not better than the Slee units. I have found that after the TT/ Arm/cartridge combination the phono stage is a definite next big stage. I like many here have found that they can either 'hide' the cartridges capabilities or bring them out.
Things like RIAA accuracy which the mags 'bang on about' is irrelevent, because most stages are pretty much the same when it comes to RIAA specs. Like any amplifier, it's how the cartridge signal is 'processed' that makes the difference.
I think it was wrong to play the A90 though a cheap phono stage and 'hope' to really hear what it is like. The Slee like many other cheap units don't image that well, have a very limited sound stage and don't sound as 'real' as the higher-end products. So, playing an A90 through that will give you the wrong idea.
Dear friends: I agree ( one way or the other ) with almost all your posts so I don't want to be redundant about but touch a little different approach.
As are different reviewers levels as are different audio magazines levels.
On the England audio magazines HIFi Choice and especially HIFI+ are IMHO at the top level and HiFi World at the lowest one and border line " mediocrity " ( could be that even that the magazine is a medicre medium one of its reviewer/contributor can has a top level as happen with top level magazines that some of its reviewers/contributors are mediocre ones. ).
Why any one want to read an audio magazine that is deep on mediocrity? just for fun? or it is that the ones that read it are at that level? or because there is no other one to read?
It is clear to me that no one of you are HiFi World readers your audio level is way up to hat magazine. No one of you can take seriously a kind of review like that on the A90.
The problem IMHO is not people like you but the un-experienced ones that read that they can mate the A90 with a " poor " quality performance analog rig.
A function/target of an audio magazine is to be a " stage to learn ", an audio newbie can learn through those kind of reviews?: IMHO they can't, the ones that can learn are all of us because we can learn or confirm how don't do " things ".
Regards and enjoy the music,
I just bought the Feb Hifi World and have had a read of the A90 review mentioned in this thread.
I agree with Robm that you need to take a liberal grain of salt with the review and need to take the reviewers system into context. However there are some good points in the review.
Noel Keywood actually measures the cartridges he reviews. Noel has voiced his systems to be ultra smoooth - his words not mine
" The MC90 has an almost ruler-flat frequency response from 20 - 20khz within tight 1db limits. Its quite an amazing feat in its own and should result in super smooth, character free treble. For some listeners used to the more typical high frequency lift most cartridges possess, the A90 might sound a little recitent, possibly lacking a little sparkle"
The measurements are superb.
He compared the A90 to the Cadenza bronze, that by comparison offers a technicolor sound".
Interestly the 2nd opinion review says the A90 has clarity at the expense of body and he had to use it with the 900 pound Icon tube phono instead of the Slee SS phono as the tube phono seemed to complement the slight brightness of the cartridge.
So he we have the same A90 cart and in one system it is too warm and smooth, and the other too lean and bright. All the A90 is doing is highlighting the sound of each reviewers system. sounds like each system needs some balancing :-)
For me the A90 is easily the best cartridge I have heard and it is that lack of high end exageration that I appreciate the most. This enables one to get into the true transparency of the music better.
