Yes, the JP 374 at 10LBS 10Oz appears to be over 1Lbs heavier than the Wessex Dolce, which weighs 9.25 Lbs.

Worth pointing out that Wessex is working on the EP600 high grade euphonium to be apparently priced in the $3K range... Hence a possible competitor of JP 374. I do not know yet when Wessex EP600 will be released... I heard positive comments about it but in spite of my hopes, I was not able to play test Wessex EP600 at ITEC... I was there only on 05/28... And the prototype was not going to be there until 05/29 *Rolls Eyes!*
