As a less expensive alternative to Parasound JC1+, one of the good choices would be the Mark Levinson 5805 integrated amp ...... Stereophile measurements show ML 5805 can handle 2 Ohm loads :-) ........

Thank you JA2 for reviewing the ML 5805 and doing the 'heavy lifting' :-) .......

Bogolu Haranath's picture

JA1 should include the ML 5805 as one of his reference (integrated) amplifiers as a part of his reference amplifier arsenal :-) .........

Bogolu Haranath's picture

Is it possible for JA1 to do the EPDR measurements in retrospect, for at least some of the class-A speakers? ...... The impedance and phase measurements are already available for those speakers :-) ......

Bogolu Haranath's picture

JA1 says, "I don't have time for that EPDR measurements ..... Go buy the Parasound JC1+ amps" ....... Just kidding .... Just kidding :-) .......

I have started doing that. The Volti Razz review now has the EPDR figures - https://www.stereophile.com/content/volti-audio-razz-loudspeaker-measurements - and I will be adding more as time goes by.

Thank you JA1 ...... You are a gentleman and a scholar :-)

TG liked the sound of Volti Razz speakers better with the Bel Canto e1X amp ...... EPDR measurements explain the reason in a better way :-) .......

I love 'stand mounts.'

They make for easy in n' out for switching speakers, which makes for awesome shoot outs!

These seem like winners.

I've been ogling the Legacy Calibre, too.

I also watch for Sonus Faber Extremas, but the have simply refused to depreciate worth a damn!

Thanks again for this review. Any chance you will keep it around for more comparisons?

Last question: Would have any working memory of the Crystal Cable Arabesque speaker for a few comparison comments?

Bogolu Haranath's picture

Crystal Cable Arabesque speakers ($20,000/pair) are certainly memorable for their looks :-) .......

Good work, man.

;-D

Another audio component whose beauty is only skin deep :-) ........

You're welcome.

Herb Reichert now has the BRXes for a possible followup review.

Too many speakers have passed through my listening room for me to be able to offer any thoughts on the comparison. Sorry.

My 'crystal ball' says, HR likes the sound of BRX with LKV PWR+ and Bel Canto REF600M ...... Both have 3rd harmonic distortion and both can handle 2 Ohm loads :-) ......

Bogolu Haranath's picture

BTW .... May be HR could do a follow-up review of the Parasound A21+ ($3,000) :-) .......

By what Sandy Gross and company pull off for the price. I don't care where its made. Exceptional engineering, design, and quality control.

remlab's picture

they usually don't measure this well. Very similar to the Elac, at least in this case

Bogolu Haranath's picture

It would be a good idea, if GoldenEar uses the same tweeter for their top model speakers :-) ......

remlab's picture

to subjectively compensate for the extremely deep bass response on the other models

Bogolu Haranath's picture

Some of the young people who can hear up to and above 15 kHZ, have complained about harsh treble in GoldenEar top models in the Stereophile web forum :-) .......

remlab's picture

Especially in how it relates to the loudspeaker's efficiency is much, much better than the Elac

and I examine everything he does with a keen interest, but Sandy's got him beat on this one.
