EAR 834P + Bent Audio Stepups = greatness?


I have an EAR 834P unmodified and am constantly reading how this amp is certainly one to be on the short list of anyone who wants a decent entry level phono. I have the deluxe version so it can handle low MC carts. When modified, many claim this unit is exceptional competing with units well past its price point. My question, if paired with exceptional step ups from Bent Audio, would the EAR perform in the same league as higher end units? The EAR has a very short signal path, is very simple so there shouldn't be much to lose from the cartridge to the main amp save for problems with the decent but not wonderful internal step ups. throwing in some of the world's best into the chain, would I see a world of difference or would money be better spent on a new phono outright? By that I mean, should I modify the unit and get the Mu's or would that $1600 or so paired with the 900-1000 I might get selling the EAR get me more on the used market?

Thank you in advance

From everything I have read and heard, the performance of step up transformers (SUTs) are VERY cartridge dependent. I have heard some very good ones, but if they work well with the cart you have now, its not clear if they will work with the cart you have X years from now. Performance is also highly sensitive to cart loading and so any SUT that could potentially be matched with more than cart should have easily adjustable and infinitely variable (i.e., not confined to discrete steps) resistance. YMMV.
The Hagerman Trumpet with the Mu SUT is a very good sounding MC phono rig, but...you will need to experiment significantly with resistance to find the right value for your cart AND it will be very sensitive to cabling, as the step up ratio, IMO also makes the cable sound like it is also stepped up in length. IOW, make sure you can keep the cable btwn the step up and the Trumpet as short as possible. Or at $3500, you are in the $ neighborhood of the ZYX Artisan phono stage that works just fine w a 0.25 mv LO MC cart, esp w a ZYX cart. When auditioned against the Doshi phonostage it held up well; w some compressing of the harmonics around the fundamental tone but otherwise very good at a fraction of the cost. If LP was my primary source, the Doshi would be the winner, but... Another option would be the ZYX pre-pre which is essentially an outboard solid state gain stage that goes btwn the TT outs and the phonostage ins.
