Are There Any Good, High Power Solid State Amps?


I feel like I'm running low on power with my current 100 watt tube amp, so I'm looking for suggestions. I'd like to try solid state, but I want an amp with an airy, rich tonality. I've been thinking either Pass (love the XA series, but I'm afraid it won't be enough power) Pass X, Krell, Clayton, etc. Can you make any suggestions (new or used somewhere in the $5K - $10k range)?
Thanks in advance.

Louis1-

You seem to be ignoring the DNA-500 - not sure why. 500W into 8 ohms, 800w into 4 ohms. The VR4's will be singing like you've never heard them before. The 500 drove my VR7se's incredibly easily - could have broken windows, eardrums, etc. w/o a sweat. I'm not a dealer, nor do I work for SMc, but the DNA-500 really should be on your short list. You can get one used for under $5K and its 1 of the best values in higher-end audio.
Here's another suggestion Louis.
Keep your 100 watt tube amp and add 2 self-powered subwoofers like the Vandersteen 2Wq with their high-pass filter. This will relieve your amp from the power-sucking bass frequencies and add 600 watts of power for the 20Hz-80Hz subs. You will find the headroom of your existing amp increase enormously as well as the performance of your existing speakers. Here is a link to The Audio Perfectionist and what Richard Hardesty says about the Vandersteens.http://www.audioperfectionist.com/pages/freejournals.html Click on 'Download Revised Journal #2 Free' and then scroll down several pages till you get to SubWoofers.
Only subs with a high-pass filter will allow your existing amp to gain headroom.
I was reading a glowing, 6 Moons review of Bryston 28B's. Doesn't seem to be your typical Bryston and is the basis for the next generation SST^2 series. Looks like they go for abut $8k used.

All of the brands that I prefer have already been listed.

However, I highly recommend mono blocks with whatever brand you choose.
Louis1,All the suggestions are good and the list is plentiful.Of course one or two will always get overlooked.
Because you feel a need for more power and to be sure the amp is also a match for your pre.I would suggest that you start a short list with only the amps you are able to audition in your system.This may not be possible if you are buying used but it would safeguard against a costly mistake.

People seem to either love or hate Class D amps. I went from an ARC tube amp to the Class D and the sound is great. Never a problem with not enough power either (bi-amped).
Louis1,

I have owned many famous SS amps, including BAT VK-600SE and Clayton M-100, and have heard many others, including Clayton M-300 and Pass XA-160's.

That said, while I agree with Tvad that I don't quite understand the need for that much power, I think the Clayton M-300's or the Pass XA-160's will fit in your price range used, and both will EASILY drive your speakers.
The BAT VK-600SE was very nice, but the Clayton and Pass are better, IMHO.

If you crave the tube sound, you will find a pair of VTL MB 450 series 1 or 2 will fit your price range, and also EASILY drive your speakers.

Happy hunting,

John
stay with tubes!

ARC Ref 300 or 220 can be had under $10k used. if you want to start lower, VT-200 can be had under $3k. my personal favorite is BAT VK-150SE. even though they only have 150 wpc, they should drive your VR-4 louder than you care to listen to.
TVAD,
You're right, something doesn't add up here. All I can say is that when I get up to levels around 95db, things get flat, and worse than that, the high frequencies seem to sound edgy....especially piano.
NGjockey,
I also heard the Bryston 28's at 2008's CES, driving some Theils. They were outstanding, and I'd pick up a pair of 'em in a heartbeat at the right price. Retail, they are just out of reach. I've never seen a pair used.

TVAD,
How do you impedance match an amplifier to a speaker? (By the way, it's Louisl...the last character is an alpha 'L', not a numeric '1') :-)

Ya, you're right. Sorry, I just glanced the headlines. Both the current 7B's and 14B's are upgraded similarly to the 28B's and are now balanced from input to output. Might still be more workhorse than racehorse but some speakers are more job than sport.
Keep the VT100 and get rid of the conditioner and the Bybee stuff. Try some PC's from the cable company and other cables if need be...you should have enough power! By the way, always use the 8ohm taps as they have better drive.
I agree with TVAD, the Pass XA60.5 should easily be able to drive that speaker. It also sounds like almost any tube amp would have difficulty with that impedance dip in the bass, there are some that could handle it, but it is not an ideal load for most tube amps.
Louisl,
I second Halcro's suggestion of getting a pair of Vandersteen 2WQ subs with High pass filter (pref. the Model 5 filter). Vandersteen's method of hook-up is unique (except for maybe Rel) and as Halcro described it takes the pressure of reproducing the very low bass from your main amp - which has a few side benefits such as increased dynamics and a more expansive and defined soundstage. The improved quality and quantity of bass is almost secondary to these benefits.I've heard speakers with far better reputations then the VR4's benefit from this arrangement.
Louisl,

Tvad is most likely dead-on to the source of your "power" problem. I have a very easy(and relatively cheap) test/solution for you...

Get ahold of some Zeros (Speaker Impedance Multiplying Autoformer) - by Paul Speltz. They can raise the speaker impedance seen by the amp bu 2x/3x/4x. So, if your speakers dip to 3 ohms and your amp is having a hard time, on the 2x setting the amp will see a much easier 6 ohm load and sail along without breaking a sweat. Read the professional reviews and customer testimonials on the website.

Best of all, he offers a 60-Day money back guarantee. So, for $450(naked) or $950(boxed) you might just find out that your AR VT-100 actually has enough power. If not, no money lost on the return.

At the very least, they work with any amp and will greatly broaden the list of what will work with your speakers. Meaning you won't have to spend $8k-$10k to get the results that you are seeking.
Hi Louisl.

Unless you have upgradeitis, you might try the Autoformer described above before spending lots of $$$ on a new amp(s).

ask viktor khomenko about the difference between tube and solid state. it is a fool's errand to think you can replicate the sound of tubes with a solid state product.

there is no free lunch in audio. if you want solid state you get the solid state sound. richness and solid state is a contradiction.
See my review of the Bel Canto Ref 1000 Mk.2 monoblock amplifier just posted on issue No. 43 of Positive Feedback Online. Yes, IMO, this is an example of an excellent SS amplifier at a Real World price.

O.K. educate me. Why has no one mentioned a pair of Belles 350a run in mono. $8K new $5K or less used. Plenty of power, clean, big soundstage. Now I'm ready, tell me why not.
