Finally made the transition to a tube preamp!


I was always curious about the much hyped sound that one can get from quality tube amplification. People talk about 'tubey magic', 'the golden glow', etc. I was always curious, but was reluctant to go in that direction because the received wisdom is that unless you spend big bucks (like, money you could buy used car with), tube amplification will only disappoint. The rationale is that with less than top notch tube equipment, all you get is a muddled sound with weak, flabby bass and rolled off highs.

My opinion started changing once I obtained Carver M-4.0t power amp. I bought it because I wanted a lot of power to drive my Magnepan MG-1 planar speakers. Once I hooked Carver M-4.0t to my Maggies, the sound was transformed. Not only did Maggies start singing, the very character of the sound drastically changed. Carver made that amp with the intention to emulate his flagship tube power amp, and by the way that amp sounds, I'd say he came pretty darn close. Yes, I started hearing that 'magical 'tubey' sound. Very exciting!

However, that's not what really changed my way of enjoying music. Intrigued by this encouraging discovery (courtesy of the Carver amp), I started looking for an all tubes preamp. Of course, quickly realized that without paying at least three of four grand, I won't be able to afford quality tube preamp.

Then, by accident, found an ad on the craigslist selling Dynaco PAS-4. Tempted, I offered $475.00 and next thing you know, I got the preamp. 

OK, so now, with Dynaco PAS-4 hooked into Carver M-4.0t, the sound is completely, radically different than anything I was able to hear before. This preamp is incredible. It seems to have it all: soft, sweet, mellow, liquid, golden glow sound coupled with muscular bass. It delivers almost frightening slam, and the soundstage is way larger than before.

Isn't it amazing that for less than $500.00 one can get such amazing sound? The only problem is, as I understand, Dynaco PAS-4 is quite a rare find. Allegedly, it was produced in the early 1990s in very limited quantities.

Bottom line, if you spot this preamp for sale, don't hesitate to snatch it. In my experience, it is quite amazing!

A friend of mine once wrote an article called 'Color Me Perfect', the jist of which is no audio product is perfect and you pick the one that fits your system and your tastes best. Neither tube or solid state circuitry is perfect and they each have their own pluses and minuses which overlap but are not exactly the same. You are fortunate to have gained more insight into your perfect colorations and the result is a system that pleases you more.

Now if you can challenge oneself to keep it as-is, and leave it, you’ll be doing well.  For others, curiosity sets in about different tubes, then different preamps using different tubes, then curiosity sets in about exploring various tube amps, and tube DACs, so on and so forth. Like others here - I enjoy an all-tube system, yet where you are now is a nice place to be if you can stay there and enjoy it for what it is. Enjoy!

oh man, theres some good tube stuff out there, old and new, and a good bit of it is afforadable. heck the audio by van alstine budget tube preamp (transcendence 10RB) is 1100 and supposedly just fantastic. i have the no-frills version of the top model. also, the used market is full of excellent line stages for well under $2k. im in the tube preamp-solid state amp club also! got a fantstic tube dac as well, the musical paradise MP-D2. my god, it sounds damn good.

Welcome aboard. 
 

I’m not certain I agree with @blisshifi  - at least that hasn’t been my experience. I find the amplifiers are more forgiving and the lower voltages in the phono and pre stages are more prone to tube noise. This is why tubes that test out with the lowest microphonics are considered necessary in those components.

Look for some Amperex NOS 6922’s.  There are several different ones out there and I found the PQ’s with the gold pins to sound excellent!

All the best.
