How important is ext. adj. for cartridge loading


Hello Folks,

A New Phono Preamplifier will soon be introduced - MSRP around $1750 - $2000

A small "focus group" questionnaire - On a Phono Preamplifier how important is it to you that MC cartridge loading is adjustable from the front panel of the amplifier? How often do you "fiddle" around with loading ? Enough to warrant the cost increase, probably about $200 for the additional switches faceplate machining etc. pricing the preamp towards the higher end of projected price?

Same goes for MM/MC switching Would external selection be preferable to a internal Jumper setting ?

Is a MUTE function desirable on the front panel as well?

MC loading is at 100, 220, 330, 500 Ohms and 47K Ohms, do you think these are OK or would you like other values?

We have designed the unit so it can be used as a fully differential unit as well with one balanced input and one balanced output, you'd need two of them for stereo, do you find this desirable? Would you prefer this mode of operation to be selectable from the outside (switch on back) or would internal jumper selection be enough?

Thanks in advance for your thought on these questions

Avaliable MM Loading of 20K, 47K, and 100K. These would realy set this unit apart for those with HOMC, MM, and MI. Rear switch for the MM to MC would be best as previously noted. External access, front or back, for all adjustments since many individuals change cartridges often and opening the unit for each change may not desirable. Ultimatly quality components over all these convenience choices.
You seem to have covered all requests and indicated what they would cost. IMHO the real question is your last one stated i.e. the pocket book vote. Going back to your original high quality sound minimal extras may actually target a buying segment better than catering to all wishes. Possible RCA plug loading options for the back, MM/MC switch, and internal capacitance or a set single capacitance and just focus on the sound. The sound quality is what will be talked about and shared, leading ultimately to us parting with what is in our pocket books.
