Audio Research Corp Ref 5 SE

Bifwynne - since the power supply and the gain section circuit of the Ref Phono 2 are shared with the Ref 5, and since the SE upgrade to each includes an upgrade to the power supply and addition of Teflon caps, you may get some idea of about the improved sonics of the Ref5SE by parsing through the Valin preview on the Ref Phono 2 SE. Since his comments indicate he had roughly 10 days with the RP2SE, further improvements will come across the several hundreds of hours of break-in needed by a new unit generally and the Teflon caps in particular. The power supply upgrade should yield better low frequency articulation and, typically, Teflon caps will offer more tonal depth. It's likely the Ref5SE (and RP2SE) will sound closer to the Ref40 Anniversary and deliver improved image focus and dimensionality. Just my thoughts as an exercise; I've not heard the SE units, but I'm looking forward to 'em.

How is the ayre KXR comparing to the ARC Ref 5 or 5SE ?

My ref 5se arrived today at dealer...picking it up tomorrow. I have a KX-R fronting Ref 250s and the ref 5 SE will front a ref 150 at my cabin.

I will let you know my thoughts on differences...I listened to the Ayre on the 150 for several months until the 250s arrived

Glai,

I did a bit more comparison between the KXR and the REF 5SE yesterday before returning the KXR to my friend. I think both preamps are excellent but thre are some minor differences and which one is better is a personal preference.

The KXR has lower background noise and instruments are better separated and the high frequency is a bit more extended. The REF 5SE on the other hand, has vocal that is more emotionally involved. I guess that is what tubes are all about. But to my surprise, the highs and low ends are more like solid state than tubes. I was expecting soft bass and rolled off top end.

To my ears, the REF 5SE is the better preamp by a slim margin. I have always been a SS guy and this is my first tube equipment.

I look forward to Tylercoupe's comparison of these two great preamps.

Think I'll wait until the REF 6.
