MC step-ups....difference between them in the Hagerman line-up

Hey Jim -

Needing a step-up soon for MC (or low output MM/Pickering or MI/Grado cartridges), but I'm a bit confused about your offerings.

You have a Piccolo JFET unit.....for $349 and $449 (fully assembled). What's the difference between them - better parts?

Then, I see a passive step-up using Cinemag transformers for $649.

How would one choose one of the Piccolo units from the passive step-up (other than for purely financial reasons).  I have little experience in either...my MC gain stage has been innate within my full functioned preamp (or I only needed an MM stage previously).

I'm kinda' veering towards the Piccolo for both cost considerations (which one I am wondering, however  :scratch:) and because it'll be largely immune to 'hum' as I have heard folks experience with passive step-ups sometimes.

My preamp, soon to arrive, will have 'infinitely' adjustable loading options from 10 to 100K via a potentiometer...but only an MM gain stage within (it's a modded Advent 300 receiver dba a Preamp/Tuner with wide adjustable resistive and capacitive loading options).

Thanks in advance for your advice!

The PICCOLO comes in blue from HAGTECH or the expensive fancy red chassis with better connectors and caps from HAGLABS.  The STEPUP is the passive version.  They both do basically the same thing, you pick your flavor.  I find the STEPUP more organic and the PICCOLO more dynamic.

I find vinyl to be the most organic software/front end of them all already...what it mostly lacks is dynamics versus it's digital competition.

Guess that makes me a Piccolo potential customer (red boxed one most likely) :thumb:

Thanks Jim - will probably order one after my new preamp arrives (a couple weeks max I'd think)

Hey John would the Piccolo step up improve the output of my Grado Green to negate me needing to buy the ADC cartridge as I haven't had a response from Mike in regards to shipping to Barbados.Regards Cleaton

Hey Cleaton/Derockster,

Probably a better way to get some gain from your phono stage is to have a good tech (hopefully you have one there is sunny Barbados) to lower the level of negative feedback and eek out a few more db gain in your phono stage.

I know your issue is getting enough gain/volume on phono with your electrostatics

Alternatively, if you have bass and treble controls and don't use them....you can have the tech bypass them (not deactivate or remove them as you might want them in the future) and you will likely add several db to your linestage (which will give you greater gain/volume for CD/Radio and Phono if you need it).  Generally, bypassing tone controls adds transparency to your preamp allowing it to act as a higher end one would/could.

I only learned of the two above methods of eeking out additional gain in the last few days...as I have a tech/modder working on an old Advent 300 (the reason I will need one of Mr. Hagerman's step-ups is that the Advent does not have an MC stage for low output devices) and we found the gain in the current phono section to be a paltry 33db and 15db in the line. 

48 db is waaaay to low to amplify teeny phono signals in my system.  Bypassing the tone controls added 6db in the line stage in my particular case...and the tech decreased negative feedback and added in another 6db in the phono stage.  Total is now 21db (line) and 40 db (phono).  This should be sufficient gain for me and my system.

The above are probably less costly and better ways of adding gain to your system - the minimum the Piccolo would allow for is 12db (don't know if Mr. Hagerman would do custom options for less than this if you need  :scratch:)

As blakep said in a post in the Vinyl Circle yesterday, getting gain matched to cartridge is really critical part of getting vinyl to sound right.  I think the above ways are better to achieve higher gain in your system (or buy the ADC which outputs 20% more than the Grado for $79 or so....but you still may find you need more gain in your preamp, amp or higher efficiency speakers)

Adding even a high-quality low noise device is probably a next best thing to do after the other options are exhausted.  An outboard device adds length to the transmission line and possible opportunity for noise to reside in your sonic chain.  A tech's time in Barbados to do this is probably less cost than $349.00 + shipping from Hawaii. That's how I'd look at it...Mr. Hagerman may have different views that would be great to hear  :cuss: :wink:

Sorry for the philosophical wanings Jim....it would be quite cool to hear your thoughts on the subject  :thumb:

Thx, John

Jim,

I noticed on the Stepup page the links for the manual and the "guts" photo are dead...I'd be interested in seeing them, and just wanted to bring that to your attention.

hagtech

Thanks for catching that missing photo.  I'll take one tonight.

There is no feedback in my tube phono stages.  Or in any of my tube phono gear.

I still can't seem to access the guts/manual links for the StepUp...the manual for the Piccolo works fine, but the "guts" link is dead as well. Not trying to be a pest, honest!  :oops:

hagtech

I haven't written the STEPUP manual yet.  Production comes first.

Cool...thanks for the heads up!  8)
