EAR 868 VS Belles 21A?

I switched out the Mullards CV4003's and put back in the 1950's GE 5814A BP triple Mica and the speakers really opened up with a more natural presentation. I can easily hear deeper into the soundstage.

Wig, I use a pair of Mirror Matched RCA 5814A from the 1950's. These tested very low Mic. and are the 3 Mica type. I got one set from Andy at Vintage Tube Service and they sounded so good I got a second set as backup. I am still using the first set after 4 years.

hello wig, i find that i like raytheon 5814a and 12au7 in my 21a. also love sylvania 12au7 (organ labeled,conn or baldwin)plus brimar 13d5

Davt,

What tubes are you running? I'm currently running the Mullards CV4003 and also have a pair of GE BP Mica 5814A that I may put back in since I believe they have better detail and soundstage presence.

I have not but I have compared many preamps to my 21A Auricap and I have always returned to the Belles. I did like a few more, the ARC Ref 3 provided a little more air, detail and was a little more musical but lost a little warmth and base, overall I like the ARC but not for several thousand more money. The same with the VTL 6.5, nice detail of the ARC, much better base, all around an improvement but at $11,500. I will be trying the new VTL 5.5 series II and would recommend trying before buying. I will look forward to seeing what you decide. PS, I found buying really nice well matched NOS tubes and stillpoints a wonderful upgrade on the belles.
