Totem Arros - Tube Amps ?


Hi,

I am trying to help my frend with a 2 channel set-up for a medium room ( 15 x 12 x 8 ). We are considering Totem Arros. Which of the following amps will be a good fit:

1. Cary SLI-80
2. Primalune Prologue 2
3. VTL IT-85

I know that cary is a more expensive one....but we wan to consider the amp that best integarates with Arros. Musical preference is Vocals, Instruments and Jazz with occasional pop.

Thanks

Bdgregory,

Sorry for asking some silly questions. What are you referring to as "High Level Inputs" and are you referring to these inputs on your REL sub-woofer ? Also, does it mean you have two pairs of outputs on your Amplifier that allows you to connect one pair of outputs to speakers and another pair of outputs to Sub-woofer ? Do you mind simplifying this and explain me in a simple terms ? Please bear with an audiophile ignorant like me.

Thanks

Most subwoofers (I believe) have 2 input options - Hi level, and Low Level. Hi level inputs take signal from a Power amplifier, Low Level inputs take signal from the preamp. In the case of low level, it's always an RCA interconnect (and on the Rel they also have XLR Balanced). For high level inputs, you connect to your Power Amplifier's speaker output binding posts, and the oter end to the "high level input terminals on the Sub. For many subs, the high level input terminals are simply 5-way binding posts. The Rel uses a special connector - a Neutric Speakon connector.

My amp only has one set of binding posts (as most do) and I connect the Rel Cable to the same posts as my speakers. It's designed to be this way - and as I said, the amp hardly even knows it's there - electrically speaking. The other end of the Rel cable (is the subwoofer end) has a Neutric Speakon connector which plugs into the back of the Sub. Once connection is made, you need to set up the crossover and output level of the Sub. This is done by setting the controls on the Rel's amp panel and is described in detail in the Rel Manual. You can download the manual from the Rel website and read through their setup procedures - they're quite detailed and will also help explain the connections further.

hope that helps . . .

Bdgregory,

Thanks for patiently explaining the set-up process. I appreciate it.

By the way, I happened to come across a link on search that details this set-up process at a high level ...but they also express their opinion about this set-up. Thought it might be helpful to you. The link is:

Thanks Grakesh - interesting they would have that detail.

As for their opinions - all of their arguments *against* using high level taps apply for a Home Theater-Movie set up (ie 5.1, or 7.1), and none of them apply in a Stereo setup.

From my experience Rel's recommended set up using high level taps is far better, and easier to tune in a 2 channel application.

I'm inclined to agree with them for Home Theater, and actually I am using the low-level sub out (though not a Rel Sub) for my HT rig. One nice think about the Storm 3 is it can use BOTH taps at the same time. That is, you can connect using the high level inputs to your main amp outputs - this augments the low end extention of your mains, AND connect the low-level (RCA) to the Sub output on your HT pre-pro for LFE.
Grakesh, to answer your question about required amp power to make the Arro's sing, 50W is just fine. I have tried it with a 20W tube amp, and it was severely underpowered, but my amp is 50W and sounds great.
