Getting into Tube Equipment


Hey there,

I have been gradually getting into vinyl and hi-fi for a while now. I mostly listen to folk, country, and some bluesy-rock music. Examples include the Grateful Dead, Sturgill Simpson, John Denver, and the Tedeschi Trucks Band.

I have been forward thinking about audio equipment I would like to have in the future. The components I am most eager to upgrade are my amp and phono preamp. For the amp, I am very interested in one of the Dynaco clones people are selling like the ST-70, ST-120 or the M-125 by Bob Latino. However, my first order of business will have to be getting a phono preamp with a volume control because these amps do not have a volume control. I would like to preface, I am not independently wealthy and do not expect to be in my life. Therefore, a $12,000 stereo setup does not seem like a reasonable option for me.

Can anyone please give me direction on either getting a Pro-Ject Tube Box DS or a used EAR 834P?

Additionally, If I could get some direction on an amp, it would be useful. Right now I own the Wharfedale Denton 80th Anniversary speakers and I really love them. The only thing I can see upgrading to is a pair of used Harbeth Super hl5plus speakers but this would be in the more distant future. Based on what I currently have and will be using for awhile, as well as my future considerations, are any of the amps I am considering a best fit?

Folks historically dismissed the Dynaco with its slow, syrupy, pipe and slippers sound that represented the typical products of the time after hearing the reinterpretations; most of it came down to a case of comparing apples and oranges. The new amplifiers got built with modern parts, which provide a night and day difference in perceived speed, openness, clarity, and refinement. Build an original with metal film resistors (and good modern caps), and you’ll hear what I’m talking about.
I've never heard that sort of sound from any Dyna! Of course, the power supplies have to be up to snuff and if not that might account for that reputation. They are plenty lively stock.
But I agree that replacing parts helps. The carbon film originals can drift in value and the metal films won't. I also replace the coupling caps. Over the years we've modified many ST-70s; usually using a 12AU7 voltage amplifier/driver circuit, simpler, with less parts than the original.
Me, either. I had the Big Dynaco Tube Monoblocks. If nothing else they’re fast, super dynamic, liquid and totally awesome sounding. After I had them modded by BWS Consulting they drove my naked Quad 57s swimmingly. A friend of mine had the reissued Dynaco Stereo 70 about 25 years ago or whatever which was also awesome, driving my Quads which by then he owned. 😎  footnote on history: I wound up buying a nice coffee table that used to belong to the dude that owned Dynaco, I bought it from his son at a yard sale. Coincidence?
Sometimes I can’t believe all the BS people write when someone ask for advice. The only valid conclusion I can come up with is that people mean well but lack experience. Thomas, of course you can build your dream system within your budget and even much less. I own very, very expensive gear in addition to collector items and lots of $ doesn’t necessarily buy good sound and synergy. You can build an unbelievable system with budget items. I highly recommend purchasing some of the older “bargain” items from the late 50’s, to the 90’s. Tons of great gear that can STILL outperform many of today’s items. And don’t discount stuff based on company reputation; many Dynaco tube amps were better sounding than companies like Macintosh or Fisher tube amps. I have about 20 tube amps in my home costing $20,000 down to my cheapest $600 tube amp and even my cheapest amp, when set up correctly will sound totally amazing and a sound to die for. My biggest advice, erase your idea of the speakers you want, and start new. listen and get the most transparent and neutral sounding speaker. Build from there. Keep it simple, don’t waste money, buy smart, research forums of old school audiophiles and stay away from people that have just jumped into this hobby in the last 10yrs. They mean well but do not have the knowledge nor experience as someone who has been around for 30 or 40 yrs.  I do own state of the art equipment but I still am quite amazed and attracted at the detail, resolution and realistic clarity of sound when I listen to my vintage stuff from the 50’s to 80’s. Get a preamp with tone controls and do not listen to the BS out there. One of my best sounding vintage preamps has tone controls, the Marantz 7 serial # 14,xxx and it sounds so super transparent and wonderful. It recently outperformed by buddy’s “New Production” $7000 BAT preamp. The Marantz is expensive but there are tons of other preamps to buy that are cheap and fabulous sounding. The secret to buying great stuff - research forums. 
Don’t laugh, but I use the cheapest tube buffer out there - the FX Audio Tube-01 - as a volume control for my woofer amp in my bi-amped system.

$30 for this tube buffer/preamp/volume control, and $650 for the Benz Micro Wood SL LOMC cartridge (bought here on Audiogon) and $650 for the Benz PP-1 MC preamp. Just putting the numbers out there to show how some systems can have mismatched components, price-wise, but have synergy and sound great.
I use a Conn organ amp as the amp for my ribbon tweeters and planar midrange/uppers. And a Nikko Alpha II for some Tannoy woofers.
