New pre-amplifier?
@yyzsantabarbara “When you get a computer laptop, server, etc from DELL for example. It comes from the assembly line in Mexico or maybe China. They do only rudimentary QA on that line (likely after final assembly.” That is not so. After completing... 
Shootout of Nos 6sn7 tubes
@tksteingraber Thanks for the thorough description of your listening impressions of the Linlai E-6SN7 tubes. Sounds like a good tube overall yet probably not one I want to add to my stable based on the weaknesses you noted. The 1982 Melz 1578s ha... 
Shootout of Nos 6sn7 tubes
@tksteingraber Thanks for the feedback on the 50’s Melz tubes. I find your observation regarding the constricted soundstage interesting. My 1982 1578 exemplars excel at soundstaging IMO. Perhaps a loss of some soundstaging is the price one pays to... 
Shootout of Nos 6sn7 tubes
@1markr Thanks for the input on the Linlai Elites. I researched those a year or two ago and got lost in the endless back and forth forum chatter about which ones were the good ones (Horizontal or Vertical lettering, etc) and whom to buy from. Can ...

@tksteingraber Please let me know how you like the early Melz and the KR 6f8g.  
Shootout of Nos 6sn7 tubes
@tksteingraber Glad to hear that you are enjoying the NU 6F8Gs. They have a very special blend of sonic attributes that I find impossible to beat. The 1982 vintage NOS Melz 6n8s/1578 tubes I bought recently are sort of a mixed bag sonically. Extr... 
Bricasti M3 vrs Meitner MA3
“The focus here is on creating a natural sound vs. hyper-realism.” @arafiq +1 @robshaw it rakes a while to fully appreciate the sonic virtues of the MA3 over lesser DACs, but you will. Plus the MA3 needs 300 hours to fully “come into voice”. Give... 
Shootout of Nos 6sn7 tubes
@tksteingraber i was fortunate to buy two of the Phillips rectifiers back when they weren’t so pricey. Perhaps someone else on this thread can recommend another rectifier with similar sonics. For now, just see how you like the KR and NU with your ... 
Shootout of Nos 6sn7 tubes
@tksteingraber IME, the KenRad VT-231 and NU 6F8G can sound a little closed in (lacking air and sparkle on top) with the Mullard GZ34 rectifier in my system. If you find that to be the case after becoming acquainted with them in your system, try a... 
Shootout of Nos 6sn7 tubes
@tksteingraber I have found that the National Union 6F8G round plates are very special tubes in my Supratek Syrah. I also have the NU 6SN7 round plates and the NU 6F8G sound better in every way. Also have Tung Sol VT-231 round plates (transparency...

Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure
@david_ten Welcome back David! You were missed. @abd1 It’s good to hear that your Nenuphar Mini’s have “come on voice”. I too experienced a VERY extended break-in period with my Nenuphar V2’s and sometimes doubted my choice during that time, but ... 
Perplexed on how single driver speakers can cover such a large Hz range
@atmasphere My ears say otherwise, but they can’t read.   
Perplexed on how single driver speakers can cover such a large Hz range
@ronboco See video linked below starting at 6:30 where Jon Ver Halen, Cube Audio’s US distributor, explains the unique engineering solutions incorporated into their Nenuphar loudspeakers to overcome the frequency extreme limitations of traditional... 
Perplexed on how single driver speakers can cover such a large Hz range
