Grado Statement Series


I have recently purchased a Statement Sonata here on the 'Gon. I currently have Rega pre with only 36.5 dbs. of gain. My question: Can I use a step-up transformer to make up the differnce in gain? Or is new(used) pre-amp in my future? My knowledge is lacking and I have searched the archives to no avail.

Colitas, That Grado Statements has an output of 0.5 mv. It would require a preamp gain higher than the 36.5 db that you are providing. 56db would be optimum gain for your Grado.

I also don't know what Rega pre you are using. The Brio, Mira and Cursa all offer phono input plug in cards, but I'm not sure if they can provide you with different gain settings by "custom tailoring".

There are a couple of options. The first one you had mentioned by getting another preamp, or purchasing a phono pre and using it in conjunctionn with the "AUX IN" input on your existing preamp.

Ultimately, if you look for a phono pre gain value of 56 db, you will make that Grado come alive.

Happy Listening, Ed.
Twl, I find it interesting that you would recommend a step up. I have always found step ups' to be somewhat problematic. It seems that any "transformer type" step up would introduce hum problems (to varying degrees), and offered little or no adjustability or versatility.

I am aware of the "transformerless" designs, but we are now beginning to approach the costs of good quality phono preamps with significantly more versatility. I think that if we were to evaluate step ups' in terms of cost/adjustability/effectiveness, would we not find them somewhat lacking?

Also, another topic that neither of us has mentioned is interconnection. We are introducing another set of cables. What's happening to our loading factors? Once again, it very much surprises and confuses me, the choice used by Rega in terms of gain factors. Unless there are varying gain settings available in their individual phono cards, you are restricted to a high output cartridge (required approx.5.0mv) w/36.5db of gain being provided). But, that has always been an issue with me, as I really don't know how some of these designers arrive at their provided gain factors.

Of course, we could also not put the cart before the horse, invert the equation, and initially purchase a cartridge that works well with the provided preamp sensitivity/gain settings such as I did with my YBA Passion/phono. But that's another thread. I have always put a lot of value in that approach. One less box, one less interconnect, one less power supply (ac or dc), one less power cord, one less "link" in a chain. But, less diversity in cartridge choices.

Oh well, life is filled with compromises.

Just my opinion, for what it's worth. Ed.
Doug, you and I are in 90% agreement. And before we discuss the fine points any further, I would like to ask one question. Which, based on my previous response to this thread, I consider highly relevant.

With all do respect, How much do those beautiful Mu's sell for in non-kit form?
Doug & Twl, You're right. It is me reading cost into the equation and maybe I shouldn't be. I assume it's the way I read the original post. I was basing my opinion on the equipment presently being used.

Although, I was NOT thinking about step ups' in the $700-$1500 range. I have had experience with both the EAR and GSP units with great results. Both also being fairly significant investments for this application.

I have always felt that once entering into that level of investment, full blown adjustable phono preamps had the advantage. In this particular scenario, it would allow Colitas to experiment with loading AND gain settings for MM OR MC cartridges eliminating the need for any step up. I was also figuring something like a Monolithic or equiv. on the used market in the $350-400 price point plugged into the aux inputs on his existing amp.

PERSONALLY? If it was me? I would be either buying a cartridge with a higher output OR contacting Rega to inquire about a 56db gain phono card, to avoid the introduction of cabling, power supplies, etc. NOT to even mention the $$$.

But, the original poster wanted options.
