Newbi seeking advise - why tubed pre-amp?


I am looking for an integrated amp for my small home office to drive a pair of Energy Veritas 2.1 bookshelf speakers, and am thinking about getting a tube integrated amp, although I have never owned any tube equipment before. I see there are some amps, such as Julida 1501 that comes with a SS amp section but tubed preamp. I understand why people may want a tube amplifier with how it handles distortions and etc, but why tube pre-amp? Why adding coloration to the signal before it reaches the amplifier? Don't you want it to be as pure as possible? This is just as confusing as tubed DACs (some Sonic Frontier I saw before). Please advise.

Well a lot of us think that tubes, whether they be in a preamp, amp, or dac, don't necessarily add colorations or distortions. Personally I think a well executed tube circuit, a la my Supratek preamp or Cary amps, is inherently more linear than SS and as an added bonus it sounds a lot better. You really ought to try it some time, you might like it. Really.
"it sounds a lot better" That is why!

For many of us, the only reason to not use tubes is if we have large, inefficient, power hungry speakers. Even then, if we have lots of money, we still buy tubed products! Of course, on a budget, the hybrid integrateds work really well.

You sound like you've never heard the huge soundstage a good tube amplifier can provide; visit your nearby dealer (Conrad-Johnson, or even Jolida) and have a listen. If you're not impressed, or listen exclusively to R&R, then your choices are simplified.

Otherwise, there's nothing like the wonderful sound of tubes.
However, even rock music sounds great with a tube system with a little bit of cojones.

I started in the same place about 8 years ago. I had a Parasound amp running off of a Sony ES receiver. I got that Sony out and put a Conrad Johnson PV-10AL in there, and I was in heaven (for a little while, at least).

That was about the time I stopped looking at specs alltogether.

Try something in your home, if at all possible, and I'd recommend either a tube pre and a solid state amp, or hybrid integrated with ss amp stage and tube pre stage.

I had a Unison Research SR-1 hybrid integrated that was absolutely badass, however I preferred an all-tube design.

Check out the SR-1, on Upscale Audio's website here, it's so cool.

very highly recommended by me.

The Pathos Classic One hybrid gets a lot of good press, here it is:

Never heard one, but it is a Stereophool "Class A" integrated, if that matters to you.

I use a Rogue Tempest, however it has a lot more tubes to deal with, but it is an auto bias design, meaning that you don't have to fiddle with tubes as much as with some other amps. I love it. Really. LOVE.

I have listened to Jolidas and enjoyed them, but since they must be user-biased (I think, someone correct me if I'm wrong) and there is a TON of difference among sound quality of their products (Probably attributable to the difference in power tubes used), I wouldn't recommend them for a first foray into tubes. BUT, I've never owned, just borrowed, so I'm not the person to ask about Jolida.

There are a ton of rediculously inexpensive import tube amps and preamps around here, for some reason, however, I have no experience with any of it (Cayin, Consonance, Radii, others). If it were me, I'd stick to a well established company with a good service record, and a repair facility in the US that's been the same for a while.
I'd hate for you to get a bad taste in your mouth regarding reliability issues of tubed equipment solely because you might not have gotten a well-executed piece.

Whatever you decide, try to get something, ANYTHING into your house. Listen. I think you'll agree that there is something magical about tubes.

good luck.
If it doesn't glow, it's gotta go! Tubes add a sense of warmth and musicality to any system, and by tube rolling you can dial in the sound to your liking. In looking at your application I would suggest something from Cayin or Opera, both very good Chinese companies.

I sold off my SS integrated at work recently (Primare) and bought this http://www.operaudio.com/Html/Opera-Products-CYBERSERIES-cyber10.htm

The Opera Consonance Cyber 10 has a toggle switch to select either ultralinear or triode mode, biasing is pretty simple as you can see by the picture in the URL. I ordered the unit with two inputs to accomodate my SAE Two tuner and heavily modded Toshiba SD3950 DVD in my office system; headphone listening is important to me seeing as I'm in an office so having the headphone jack and/or a line out to add a headphone amp was a must have (Senn HD600 cans with Cardas cable). Speakers are Totem Rokk with QED Silver Anniversary wire. How does it sound? No idea, I've been traveling throughout Asia for the last three weeks but my boss who is a big time 'phile set it up and reported back to me...

"Very nice unit and sounds good too. I connected the CDP and the tuner in input 1 and 2. Speakers are at 4 ohm. I played some Dark Side of the Moon. Good pick!"

I'll write a review once I put the integrated through it's paces and have a good feel for it's character. Keep an open mind and have some fun with tubes! Best, Jeff
