tube amplifiers, unless very high-powered, simply do not produce tight, deep bass or dynamics. A good SS amp can be a s smooth and mellifluous as a tube amp but provide a more balanced overall sound.
It's been a while since we talked about our amplifiers (23 months in fact). So we'd like to know what you are using now and why you like it.
Since I like large scale music, be it Tchaikovsky or Pink Floyd, I went for tranistors. My Proceed BPA2 has some of the same parts as the Mark Levinson amps, and the same sonic signature. I couldn't have gotten enough muscle in the lower octaves from tube amps in that price range.
Sure, Valve amps don't sound realistic, but neither do transistors, and neither do any loudspeakers. In many cases, there is no musical event to be realistic to - and realistic reproduction of the master tape means buying the same amp and speakers used to record said master tape. Valve amps, with the right speakers are an aesthetic choice that looks and sounds great. My system produces an enjoyable, dynamic sound that is clear and non-resonant. It's also completely non-tiring or annoying. Not all recordings sound great on it though. But most recordings sound very good.
I use the tube driven STAX OMEGA-II Earspeaker System. I had the opportunity to compare the tube & solid state & I found the tube driver sounds sweeter & more engaging than the solid state driver. The tube driver sounds wonderful on vocal, strings & piano. Just a little weak on the bass, which is not a problem at all with me.
I use Mark Levinson No. 383. I don't need the power to go all the way down to 1 ohm, and this is the best-sounding alternative to separatesplus, all I need is one extra interconnect. Although expensive, you would need to pay about twice the price to get noticably better sound.
I have a McCormack Power Drive DNA 0.5 Deluxe Edition. I purchased it following a very favorable review. I wanted something with moderate power and very reliable. It works well with my tubed preamp(Conrad-Johnson). I have had it for about 4 years and it has worked faithfully. It just keeps sounding better and better with age.
I don't have an unlimited budget, so a stereo amp is almost mandatory. But frankly I prefer solid state. I've heard some good tube amps, but good solid state gear just plain sounds better, with more inner detail and authority. When you add in lower cost and reliability, the only amp I'll use a tube in is my guitar amp.
I wanted good sound at a budget price level. My dealer recommended two solid state integrateds: the Arcam Alpha 7 and a Cambridge Audio model. Both offered terrific sound. I chose the Arcam for its MM phono section. I did not audition others because the next nearest high-end dealer is several hours away. I am completely satisfied with the Alpha 7. It performs well with the various genre of music I enjoy.
I don't have a true multi-amp system, so to speak, but I did not see "both" listed above. You see, I switch off between a tube dual-mono amp (upgraded Music Reference RM9) and solid-state amp (Monarchy SM70 Pro, Class-A single-ended Mosfet), depending on my mood. The tube amp has more of the deeper, rich tube sound, with excellant ambient retrieval, while the Class-A solid-state has more punch and quickness to it (but still liquid sounding for a sand amp, Class-A gives it that magic). This amp suits me when I want it a little punchier and more "rocking," so to speak. Both are wonderful sounding amps that I have no desire to part with, or choose one over the other.
I use a Krell KAV-500, and it plays my super efficient Infinity Composition Preludes just fine. I like both music and movies, but really enjoy the concert videos like Casino Lights '99. I purchased my amp due to a recommendation from Robert Harley when he was a reviewer for Stereophile Guide to Home Theater. I purchased the Preludes from a review in Stereophile. While I heard neither prior to purchase, both turned out to be the best audio purchases I've ever made. I'm content.
Come on, folks, get a life. It's just an amplifier. Do you really think that at the time of the final tally, any of this will make one bit of difference? Of course not, so just sit back, and learn to enjoy what we have, which, as far as I can see, is the single biggest problem this hobby faces.
