JM Labs Electra 937Be vs.Diva Utopia Be vs. Mezzo

Just got back from the audio shop this afternoon and had a fairly quick audition of the Electra 937. Very impressed I was. I was hoping to do an A/B comparison with the Diva, but for a variety of reasons was unable to do so. Perhaps will have a chance later.

I've now checked out the 907 and 927 Be, the first of which I liked a lot and the second of which I thought was disappointing. But the 937 is a whole different matter.

What I'd like to know is if others have made these comparisons as well and what were the impressions. Also how do the 937 and the Diva compare with the older Mezzo Utopia? If you had a choice, which would be the best choice and why? I had a very, very brief audition with the Mezzos a month or so ago, and liked them, but I didn't have a chance at that point for a full check with my own music. I'm still pretty blown away by the beryllium tweeter, which is just amazing with my musical tastes. Could someone also explain in more basic terms some of the technological distinctions between these three speakers? Thanks in advance.

Washline you summed it up the cabinet`s on all the product`s in the Utopia series far surpass the 900 series. I am a JM Lab`s fan and have lived with the Mezzo`s for a couple of years. The old Utopia`s cabinet`s are lead lined for dampening purpose`s the new BE serie`s have been redesigned with stronger braceing and the lead has been taken out. Is it better? I have listened to all of them excludeing the Grand`s. Do the new BE`s sound better? My ears say no but they do sound a little different. I don`t fall into the hype of every (new and improved)product is better although it most certainly more costy 2to3 K more. Go with the Mezzo`s and save yourself some money, on the used market I`ve seen them as low as $4500. Just my 2 cent`s David

thanks for that reply David. I agree that the Mezzos are a pretty great speaker too. But I don't think the beryllium tweeter is only hype. I think JM Labs went to a lot of work on that one and produced a very clear, very dynamic tweeter. I'm still going to consider the Mezzos. They are indeed very well-priced. Thanks for the reply.

I started with MIT T2 biwires and still have them. I tried Nordost Flatline MkII, Audioquest Granite, and Kimber 4pr.

As for system components, you can see my "system" link.

Keep in mind in the 70`s Yamaha made the ns-1000 speaker`s which were the first to use beryllium in the cone`s the process proved to be quite a diffacult and costly process for them. Selling off there manufacturing equ. to TAD. So this is nothing new, allthought it most certainly does have great benefit`s for stength and wieght issue`s on the tweeter cone`s at higher hrz 50K.All I was saying JM Lab`s has redesigned the Utopia line saying it`s new and improved and BETTER raising the price 2to 3K. I feel JM Lab already made a very fine product. David
