Transitioning: back to solid state....


Quandaries and time consuming frustrations...

This is a derivative of one of those tube vs. solid state amps. And, good god, I never thought I'd start one of these types of threads.

I've started some pretty stupid threads on audiogon, but this one might take the cake.

Anyways, after clicking my virtual system link, you are well aware that the centerpiece of my system is the not-so-reviewed and not-so-popular, the lowest of the low of all ARC amps, the CA50 integrated amp.

It is my first tube component, and I am in the process of replacing it. Tubes are simply a hassle for me, and, being too ignorant to know how to bias tube amps, I'd rather get a solid state. This way, I won't have to worry about purchasing megabuck NOS tubes or having to replace worned out tubes. Oh, and I'd love to leave the amp on ALL da time.

I've collected quite a lot of data in my cerebral databank about the solid state amps capable of replacing tube ones and are under $2000 used. The hit list includes Pass Alephs 3 or 5, 47 Labs' Gaincard, Bel Canto Evo 200.2, and Spectron's Troubador.

One observation I made when doing my research, besides the Spectron, Pass, 47 Lab and Bel Canto has received tons of reviews from professionals and amateurs alike with a one standard deviation of the population favoring each of these (That is about 95%). A great deal of these reviewers, including the professional ones, even tout these solid state amps as comparable or better than megabucks solid state amps and capable or residing comfortably in a tube lover's system as well.

With all this in mind, I've made the assumption/fallacy that I can replace my modest lowest end ARC amp with one of the fabulous solid state amps with improved sonic quality and ergonomics as well.

Assumptions, hypothesis, fallacies, whatever, they need to be tested, and, today, I did just that. I plopped down hard earned college tuition on one of the solid state amps that is mentioned.

What do you think is the result?

This would open up a whole other can of worms for you, but here goes: One other thing you may want to try before you sell your CA50 is to put a good pre-amp between it and your source (you said you were using it direct). Even though many players have either digital or analogue volume controls, some are just not as good as others and you may be experiencing some degradation in that link (especially if it is a digital volume control - I don't know much about the Meridian DAC in your system). Yet another consideration would be to consider sending your ARC to Steve Huntley (formerly with ARC and Wadia) over at Great Northern Sound. He does extensive upgrading to ARC gear which I can personally reccomend. I had him do his standard upgrade on my ARC LS2B and it was worth every penny! He also works on Wadia and other makes as well. Their URL is www.greatnorthernsound.com. I guess you can tell, I'm just too big a fan of tube sound to give up on the idea of letting go of a good thing (though I can't say I've heard the CA50 I somehow doubt is is any slouch). It seems to me you have to pay a significant amount more $ in SS to try to achieve a similar sound. If you leave your amp on occasionally and shorten the tube life you'd be putting some of those $ towards that habbit...but you'd have that wonderful holographic tube sound, and no regrets! If you think about it the average power tube lasts around 5-10K hours depending on how hard you drive them. If you left your amp on every day for 12 hours a day that's a minimum of 416 days of life. That's over a year before you have to replace your tubes given your habit of leaving your amp on. Needless to say, I determined that small investment was worth it to me, and my amps at work stay on most of the day all day. I just hate to see you give up on tubes so easily!
How many amps are you going to but before you conclude what everyone else already knows? And what about the 518? Is there a SS amp that can tubify something like that? Last, for the love of god, please don't talk about scientific method or statistics.
Hey Jax,

I've actually been pondering the same exact thing that you've "opened," this being slotting a tube pre- between the digital front and the current solid state amp I am using. However, here is another can of worms, the aesthetics side of my don't want to go there. However, just for experiment, and when I have time to do so, I might slot the CA50 back in the system and use it as a preamp just to hear how a tube pre will improve this system. But, numerous postings on audioasylum preaches against this method claiming things from "it defeats the purpose of getting this amp," to "I've tried it with and without a pre, and it sounds the best by going direct."

And, this leads to another can'o worms; this being the scientific method, and I'd you can't leave statistics behind. Just how MANY SS amps am I going to buy before I come to the conclusion that everyone knows already? Actually, I have no idea how to answer this question except by asking this: just how many amps did all of you guys owned in your life time? I will tally all replies on a spreadsheet and find the mean and standard deviation. If the central limit theorem rings true, I should be close to the mean.
Viggen, the CA50 has a SOLID STATE pre amp in it! So if you are talking about going direct into the CA50, you are bypassing the pre amp? Just some Junior moment?
I had no idea that the CA50 has a solid state preamp. I read somewhere that it has a similar pre- section tothe LS15. But then that info might be wrong.

Regarding me wanting to go direct into the CA50's amp section, if you read that somewhere, it sure wasn't from this thread.
