How's the Synergy between Lamm1.2ref and AR REF5

No reason this should not be a superb match.Btw,Kur tank.....Those pricey tubes you and your pal splurged on,where actually a "supeb" investment in sound!

I did a little tube survey a few years ago,in my phono stage(of then)and the Amperex CCa's reigned supreme,by a big margin.I tested numerous alternative mfgrs.All the usual suspects.

Most were fine,but those Amperex tubes(mine were a small fortune too,but tested better than any others we knew of....they were really special) were amazing!!...I came just short of getting myself the Pinched waist variey,only because I wanted a matched set.You know how hard "that" is -:)

You are a fortunate fellow.

Good luck

I briefly owned the Ref5 and while I thought the mids and highs were nice, I thought the bass was so soft it was almost laughable, but I do wish I could hear it with the Lamm M1.2 as it has much better bass than the amp I had back then.

I wish I have a chance to try pinched waist Amperex 6922 tubes but I never even seen one myself. I did tried Blackburn Mullard NOS and Holland Philip/Amperex NOS tubes in my LAMM M2.2.
Basically what I would really like is a tube with Mullard midrange warmth and extension at both end of Amperex. It was suggested to me that I should try French Mazda 6922. I find it to be a good compromise of both tubes. Pretty much identical extension of Amperex with very nice warmth in the midrange but not so thick like Mullard. I am still looking around for more 6922 to try, if I ever find 2 pinched waist amperex, I certainly would like to try them and also Siemann CCA. Thanks god I only need 2 tubes :)

Suteetat, Try Telefunken 6922/E88CC or 60's Siemen's 7308. The former offers excellent balance of extension, articulation and natural harmonics; the latter has very nice extension (hi & lo) with a hint of warmth, more neutral than cool.

Thanks, I will be looking for those. A friend has a stash of Siemen CCA that I have been begging to try!
