I do agree: 9 of 10 times, you do get what you pay for...
Not so much is "wrong" with the SA250. (I had a friend do some updates/fixes, and it has improved over the original, too.)
For the price, it just is not on-par with my Monarchy or Plinius equipment.
Also, at $2400 for the setup (Sc-26 and Sa-250), they are not near the value of the Cambridge 640a. We're talking about a $450-ish integrated vs. a $2400 preamp/amp here.
I'm not saying the Cambridge is a reference unit, just that it is VERY VERY good, especially at moderate volumes. It is also 100% devoid of noise, even with the knob at 90% full volume. Try that with the Sc-26 pre and Sa-250 amp (or even my $2000+, modded B&K preamp, unless it's on passive mode).
The CJ Sa250 IS much better than the CJ Sc26 preamp which I bought to accompany it. A simple,$90 Axiom passive preamp kicks the Sc-26 pre down the block. (Sorry CJ.)
The fact that Conrad chose to differentiate the series by calling it "Sonographe by Conrad Johnson" is proof in itself that CJ wished to seperate it from their Hi-Fi lines.
I will also agree that Arcam's Cd players are great! (As are most of Arcam's fine products.)
I'll have to say that the Rotel Cd 980 transport is a bargain "upper mid-fi" unit. It is also just my transport. My DAC was another $2k+ when new. My Rotel transport, though, has been heavily modded, and I will not get rid of it until it begins to smoke! It is almost there, unfortunately.
I'm not a huge fan of Rotel's preamps and amps, just their CD players (Phillips-based, basic, and good 75 ohm digital outputs).
It's funny that this thread is still generating replies! I was quite excited about the value of the 640a Cambridge back when I bought it. At $400-$500, nothing brand-new can best it. I still feel this way, but, as I said, it is not my reference! (We won't even go there...)
