New cart, step-up or ???

Just got a Hagerman Trumpet to go with a Joule LA-100MKIII I recently acquired. Analog front end is Benz Glider L2 (0.25mv)/OL Silver/SOTA Star Saphirre. The Trumpet has 44 dB gain, the Joule 11 dB. I have run it as is, and the volume is fine at about 11:30-12:30 rotation on the Joule. Hagerman recommends his 20 dB step-up instead of his additional gain stage; or I could stand pat, or I could go to a new, mid output MC. Recommendations?? If a new cart is in the offing, what is a good match. Price of the step up is $850, addntl gain stage $500 plus 2 way shipping, cart would be less salvage value of near new Benz ($300 +/-?) What say you, analog gurus? TIA
