Shelter 501 II owners: how long is the break-in?


Hi
How long it took for your Shelter to fully break-in?I have mine played for 10-12 hours already and noticed a little bit of improvement but it is still sounds kinda tiny.Thanks.

Wow, just mounted this brand new and up and running on an MM7 playing my original mint copy of Roxy Music's Live EP. Everything sounds excellent and no flabby bass at all, just solid sweetness extended up and down all around. If the cart stays just like this I will be happy. Hard to imagine at this early stage how much better it is going to get. More to come after I pick my jaw up off the floor, that is if I can find it. So, so much better than the stock Goldring that came with this deck.
I am running a Mac 402 Amp, a Mac 2300 Preamp, using the MC tube Phono stage in the Mac with my Shelter 501 II. I have about 75 hours break in time so far. My Shelter still sounds tiny and the base isn't coming on like I hoped. I previously had a Denon DL160 that to me sounded a lot more natural. I still have hopes of it getting better since it was reviewed so well.
I know people are going to yell, but the problem is with your preamp not having enough gain on the MC...it's rated at 60db for MC......the Shelter has a very low output and you should be using a phono preamp with higher gain for MC...more like 70-75db. The Jolida JD9 has that kind of gain, as do others. I auditioned and bought the Shelter and it's fantastic on my Amadeus TT.
Output of the 501 Mk II is 0.5 mV at 1kHz 5cm/sec., certainly not "very low" but rather medium output. 60 dB gain should be sufficient as long as noise is not excessive and input impedance loading is correct.

Sheesh..knew this was going to happen. OK, I am reading directly from the "Technical Data Model 501 II" sheet that came with my 501.

It is rated at 0.4mV at 1kHz 5cm/sec

It goes onto say that "Because output voltage is low, step-up trans or head-amplifier must be used to strengthen the signal".....

When I ran the Shelter with a phono pre-amp of 60db or less gain, I felt the cartridge sounded "soft" in the bass and lacked any punch throughout. I also had my dealer recommend to me to use a phono pre-amp with ample gain.

This may or may not solve the problem with bobandcathi.....but I suspect it is.

I hope there is someone here that has ran a Shelter with a Mcintosh preamp with good results....that would happily prove me wrong. Until then, I stand by my convictions on this. I have ran my Shelter with 4 different phono preamps and I talked extensively to two different dealers in California and an experienced technician who has a lot of experience with Shelters....and the message I got was pretty consistent. It's a great cartridge, it is low output and needs ample db gain on the phono preamp to come alive.
