Ditto to Wolf’s opinion of the 12 wpc Inspire . ABSOLUTLY amazing . But what really blew me away was Dennis ! 6 weeks ago , I was playing a new matches pair of Gold Lion KT-77’s ( 150 hrs ). I heard a pop , then another , fairly mild . Shut my stuff down and went to bed . Next morning , I switched the 2 tubes, installed a different driver and rectifier . Turned on my system and just let it sit there with the CD on pause. About ten minutes in , a pop in the other Chanel . So as I watched the amp and contemplated a bad tube , Kaboom ! At about 100 dB. Dove for the switch . No light show , just a trickle of smoke from the chassis . Pulled it apart and I had completely destroyed a couple caps , a resistor with such force that it snapped the terminal strip . I emailed Dennis , HELP ! 30 minutes later my phone rang . He said ship it to me and I’ll fix it for free . I said it’s 18 months old and it was my bad tube . He said , It never happens and I’ll fix it or build you a new one for free . I shipped it to him and it was home , fixed and return shipping for free in two weeks. I begged Dennis to let me pay him . He reluctantly said OK , 100 smackers ! How many times have I met a man like him ? Not enough . All he cares about is the Audiophile enjoying his music . Try his amp . Like I said on his EBay feedback - BEST 12 Watts I’ve ever heard ! Then I went to a lower rectifier and the KT77’s and Heaven . Imagine what top notch Mullards would sound like ! I do have NOS 6550 Tungsols , amongst 5 other pairs of various values . And the tube selection for my pre ! Same results with the single E88CC Tube in the gain stage of the Inspire . Flipping Sweet ! It would sound amazing with a good pair of small speakers and stands , and subs !
For tube sound, which is more important: preamp or power amp?
I have always loved the “tube sound” - warmth, midrange, soundstage. Through the years (since about 1975), I have owned many tube and solid state amps and preamps, in various combinations. Presently, I have a tube amp and a solid state preamp. But like most of you, I am thinking of making changes, again. Not to cloud the discussion, the specific brands are not important. I also listen to acoustic music, females vocals, love mini monitors, EL34s, NOS tubes, and don’t care that much about bass. So you can see that my taste fits the tube sound very well. But I have had systems that are too warm, not enough dynamics or details, and fat in the low end, too.
okay, now to the discussion. To produce the tube sound, which is more important: the preamp or the power amp? Let’s talk in general, and (if possible? May not be) not tied to one specific piece/brand/model of equipment. I know there are exceptions to any general rule. Not sure if it makes a difference to your comments, but I have no phono and am running line stage only.
As an attempt to prevent the conversation as going in a big tangent, let’s assume equality of price/quality. i.e. not comparing a $10k power amps contribution to a system to that of a $1k preamp. Let’s also assume that the amp (tube or solid state) can drive the speakers just fine, such that compatibility does not limit the decision. And ignore mono blocks versus stereo amp differences.
two follow ons: I have the perception that preamps give you more bang for the buck - meaning that it takes less money to get a great tube preamp compared to a great tube amp. Agree/disagree? And second, I have never owned a tube dac or CD player, and will assume that tubes in either of these is less critical than in a preamp or power amp. Agree/disagree?
i am interested in your thoughts.
