Try a 6sn7 in the input tubes. I use Sylvania red label.
Cary CAD 805AE 845 300B Tube Question
I have a Raysonic 128 CD Player, Cary SLP-05 Pre and 805 CAD AE amps, and modified Paradigm Studio 100 v2 speakers (replaced caps and resistors in HF crossver and replaced tweeters with Scanspeak D2905/9500). Smooth and no problem with loudness. Can now play without compressing the highs. 28 x 22 room with speakers on long wall with front 5 feet from wall. Zu Varial IC and Wax speaker cables.
I have replaced all the tubes except for the 845 and 300B in the amps. Amperex PQ white label in CD player, Mullard rectifier in the SLP-05 power supply, RCA VT-231 in SLP tubes 1 and 2 for single ended output, and Sylvania 6SNLWGT for the input tubes in the amps.
I have tried the 211 tubes that came with the amps and they sound good but I prefer the more reserved sound of the 845s versus the more forward sound of the 211s.
The question I have is does anyone have experience with how different 845 and 300B output tubes work together. I am looking for the typical things, richer depth of sound, more "attack" or the instrument being right there in the room. I have Herbie's tube dampers but the sounds get too sharp and "un-natural" when I use them on the CD 6922 tubes.
I would be reluctant to spend $1200 on a pair of Aperex 845 tubes or Western Electric 300B. The Shuguang 845M metal plate and Treasure tubes and 300B and other brands are in the $300/Pair range and Sophia Electric are $500/Pair +/- depending. I have read JJ tubes won't fit in the holes in the 805 chassis. I would welcome any combination suggestions of tubes you have used and what sound would be expected from them.
Thank you for your help.
As an aside, is it normal for the the chassis of the 805 to get so hot you can only hold on for about 5 seconds on the 845/211 switch side after two or three hours of playing? I can hold my hand on other parts but still very warm. Good winter is coming up.
Thanks again, Mike.
