Title: Best tubes combination? Post by shootingstar on 12/18/13 at 09:06:36 What kind of tubes has given you the best combination for warm, dynamic sound with tight bass? |
Title: Re: Best tubes combination? Post by JD on 12/18/13 at 12:40:21 I'm using nos '56 rca 5r4gy for rectifier, nos tele e88cc in the driver position which I find is the most important tube for sound change and nos tele 7dj8's for the other two spots. I've also enjoy nos ediswan 6922, and nos mullard 6922 in all 3 positions. Tele e88cc is my favorite. In my system it does what you ask. JD |
Title: Re: Best tubes combination? Post by marky on 12/18/13 at 22:43:42 Great choices JD. I haven`t got round to rolling the 2+ yet, Bugle b 6dj8`s in the 3 signal slots. The driver position as a 1 tube change is a very attractive roll thats becoming more apparent. |
Title: Re: Best tubes combination? Post by Lord Soth on 12/20/13 at 03:16:44 For my CSP2+ (&CSP3), I have the following tubes in place. 1x Input tube : Amperex Pinched Waist 6922 Reason, Amperex USA tubes have warm mids, tight bass and a sweet treble. A normal Amperex 6922 is more cost effective and will do an equally great job here too. 2x Driver Output: 2x Siemens E288CC The E288CC creates an immense and immersive soundstage. It counteracts the only weakness of Amperex tubes, which is a slightly narrower soundstage. The mids from the E288CC are also warm. It has the sonic clarity of a Siemens CCa. 1x Rectifier: Brimar 5R4GY "D" Getter Reason: This British rectifier creates nice warm mids which have a hypnotic presence. Cheaper alternative would be a Philips 5R4GYS sold by Upscale Audio. As usual YMMV, I'm using pure silver interconnects and speaker cables so I always favour the use of warm tubes to tame the naturally bright sounding solid state DACs. |

Title: Re: Best tubes combination? Post by Lon on 03/30/14 at 03:59:04 I've been doing some system tube-rolling lately. In the CSP2+ I always come back to the same combination that gives me just what shootingstar talks about: warm, dynamic sound with tight bass. For me it's a 'forties RCA 5Y3GT, three 6N1P. I have been trying an Acturus 5Y3GT that is pretty old as I have had amazing success with Arcturus OA3 regulators, but it is just too inaccurate, at least so far. These tubes in this CSP2+ with the Jupiter caps . . . well, this is just the best preamp I've had. |
