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?

Hi Again,

Just to let you guys know, I solved the low end bump in my system as indicated earlier in this thread.

Right about the time I was going to leave the house to get some lunch, I thought, just for fun, I'd bi-amp my speakers with the ARC on top and, oh might as well say it, the Pass Aleph 3 on the bottom.

First 30 minutes impression: with all 45 watts of the ARC driving the HF of the Tannoys, the highs has never been free-er and open sounding with mucho more detail. with all 30 watts of the Pass driving the LF, the low bass was non-existent, but the midbass was creamy smooth with lots of presence. One thing about the Pass, you instantly feel a sense of energy in the room once you turn the amp on even without any music playing.

When playing my usual favorites such as Ivy and St. Etienne, the lows were a bit anemic. Thus, I plugged the Meridian 518 into the chain between the 500 and 563. The 518 smooths out the highs a bit and makes the lows more robuts. This was needed with music with more energy. However, when playing conceirtos such as Ryuichi Sakamoto's 1996, I prefered the sound without the 518.

After 30 minutes: The Pass now warmed up and is no longer anemic. It now provides a clear, liquid smooth mid range to mid mass with just enough low bass. I am not a big fan of low bass as you can tell.

Now I can listen to St. Etienne without the aid of the 518.

Anyhow, my system sounds incredible now, so I don't think I will be moving away from tubes just yet. I will, instead, invest in some NOS tubes to make the high-mids more sexy if that is possible then go from there...
Update:

After purchasing Bogdan's silver cables, I've re-auditioned the amps I have. The Gaincard sounded less solid state. The ARC CA50 has less ear fatigue. And, the Pass now sounds incredible even without the CA50 bi-amping the HF.

Now, I use the 518 as preamp, and the dac directly connects to the Pass Aleph 3. Also, I am using a Mapleshade Doublehelix powercable on the Aleph instead of a Virtual Dynamic P2.

The Bogdan and Mapleshade combination really improved the Aleph amp so much so that I think I've successfully transitioned away from tube and back to solid state.
Viggen, glad you found something you like. Did you ever bias your CA 50?

P.S. Your buddy(MR. EL34,you know who I mean) is posting again! He must have laid low for a while.
Hey Max,

I did play around with a few borrowed voltage meter from work. We have lots of industrial engineers there that know what to do after reading your email. An amp that still uses tube technology impressed those old guys quite a bit. And, the CA50 still sounds great. And, I've been quite happy regarding my ownership. But, as for reasons I've listed all over this thread, I rather go with solid state. And, yes, Mr. EL34 has resurfaced...
Viggen, I can't remember if I told you to let the CA50 idle for about 20 minutes before doing the bias adjustment?
