How much difference will a phono stage upgrade make?

12hz, before you start dropping coin on a new phono stage, you may want to look at the load resistors in your current model. Replace them with Vishay foils and you will be shocked at the reduction in noise, and improvement in low level detail without changing the frequency balance.

would agree with photon46, spending a lot more does not mean better. Have dropped 6K on a phono stage only to find out it was not as good as what I had.

the EAR 834s (real and clones) are also really good.

@12hz - it's been 6 months now, did you end up with the Chinook? If so, how are you liking it over your previous stage?

Also, was curious if you gave any thought to one of the E-Glo stages from EAT - since you could then share their Linear Power Supply for the phono stage with your C-Sharp? I'm currently considering this setup myself, as I also have the C-Sharp...

Thanks

12hz, this is a sideways answer to your interest in the Chinook.

I owned a Manley Jumbo Shrimp and Snapper amps for a couple of years.  I was very pleased with the sonics of both but a problem developed with unstable bias in one amp.  I lived in SoCal then and ended up taking the amp to the factory for repair.  It was a weird problem to diagnose and required two tries, but I was still pleased by how fairly they treated me (it was out of warranty).  

Also I was able to take their factory tour twice and I was quite impressed by their operation.  Also I've spoken with EveAnna a few times and enjoyed her enthusiasm and knowledge.

I do not have direct experience in auditioning the Chinook, but have no hesitancy in recommending Manley products.  I believe they are a first rate company.

I will also say I've auditioned Herron electronics at shows and a friend's system, as well as talking with Keith.  I've been impressed by him and his products as well and endorse them if they fit one's budget.

A good phono section will have less ticks and pops even though it is wider bandwidth. Its always nice to find out that your LP collection isn’t as bad off as you thought it was.

What most people don’t realize is that the phono preamp, in addition to enough gain and proper EQ, must also be stable and resistant to Radio Frequency Interference (RFI). This is because a significant amount of RFI is generated by the cartridge itself in the form of bursts of energy at the resonant frequency of the inductance of the cartridge which is in parallel with the capacitance of the interconnect cable. The RFI can cause ticks and pops due to overload of the phono section input. That resonant peak I mentioned can be about 30dB!!


Many designers don’t realize that- hence phono sections that don’t deal with this issue very well.

A side benefit of RFI immunity and stability is that the cartridge no longer has to be ’loaded’ to sound right. This allows it to be more supple and can thus trace high frequencies easier. IOW loading a cartridge causes it to do more work and that in turn stiffens the cantilever, just like shorting the terminals of a woofer makes it stiffer.

I lost 50 IQ points just reading that one. On the bright side though I don’t need to clean my records, just buy a better phono stage. So I got that going for me.
