Tube CD player and no pre-amp

Hey,

Currently, I am using Cal Audios transport and dac. In between, they are connected to a Meridian digital preamp that attenuates the volume in digital domain. The dac then connects directly to the amp. This lacked a little bit of drive, as Hawaiikid advised, but sounds super clean and detailed. However, upgrading the powercords to the transport restored the "drive". In my case, I am using a Virtual Dynamic powercord. My system no longer begs for a preamp.

I run directly to my Mark Levinsonm 335 with a Mark Levinson 39 and it sounds amazing the 39 has an anolog volume control so when you turn the volume down it just gets softer but still has all the dynamics. If you go with a digital volume you will lose bits of information as you lower the volume Good Luck

I will get rid of my Bryston and get a tube preamp. The Ah! Njoe Tjoeb opened my eyes to something that is different. Most fun I have had for the money. I want to get the op-amp flavor pack they will have. It's only about $60 they said, and will give me three more sets.

The output voltage can be changed on the Tjoeb, and I will try that to use my second set of speakers.

As to the "preamp vs no preamp" question, I get asked this and the answer is you do not need a preamp except for a few things:

To add "color" - preamps ARE colored usually, and there is nothing wrong with color.

To adjust balance and add function, and switch between components. So people go back and forth. It's nice if your CD player gives you the option to "play"

IN answer to your "Tjoeb" question , the Njoe Tjoeb has a very low output impedence, so it will run most any amp, and even long interconnect cables. The output impedence is under 250 ohms. Plenty of voltage at the stock 2.5v out.

The volume control is done in the digital domain, so you should try to keep your normal playing level towards top of the Tjoebs volume control.

If you have an amp that needs very little voltage to drive it, this would not be possible. Except with the Tjoeb. Inside there is a maximum voltage adjustment. 5v, 2.5v (default), 1.25, and .75. This will allow you to get to the point you need.

There is an op-amp kit that will be available at cost for the Njoe Tjoeb 4000. They plug right in, easy. You will in essence have three more flavors for about sixty bucks we guess.
