take the 1027Be without hesitation.Without a doubt.
But these these need a solid state amp with "current" balls. It said they measure much like the 1037Be

(fig.1) indicates that it is a demanding load for the partnering amplifier in the lower midrange and bass. Not only is there a minimum value of 3 ohms at 33Hz, but there is a combination of 4.25 ohms and –47.5° capacitive phase angle at 27.3Hz. Fortunately, music with significant energy below 40Hz is relatively rare, but an amplifier that has no trouble driving 4 ohm loads at high levels will still be required. The fact that the impedance remains above 10 ohms for much of the treble means that the 1037 Be will tend to sound shelved-up in the highs with tube amplification.
