Q: When will Sensationship?
A: Sensation will ship in early March on a first-come, first-served basis.
Q: What Sensation model is being offered in 2010?
A: We've upgraded the original Sensation design for 2010. It is a 30v unit capable of 87wpc and high-current surges from battery and linear power supplies. It features a huge, low-ESR, quad pole Panasonic bulk capacitor and is awesome!
Q: Will Sensation have issues with FM radio reception?
A: FM radios within 4 feet of the unit may experience interference. We have not been able to completely eliminate this issue.
Q: Can I run high-level speaker outputs to my subwoofer?
A: Some subwoofer cross-overs will destroy the amplifier. Please use the provided line-level subwoofer output. If you prefer to run stereo subs, you can use the stereo pre-outs for subwoofers instead of the mono (summed) output. Sensation also has stereo pre-outs.
Q: Is there a way to bypass the volume control to use Sensation strictly as a power amp?
Q: Do your amplifiers work with UK 240v mains electricity supplies?
A: We are using universal power supply units that should work in the UK, Europe, and elsewhere. We do not provide international plugs so you will probably need to buy your own locally. The 24v and ultra-premium 30v supplies use IEC connectors. The 30v/90w supply usines a "figure 8" type connector.
Q: When the amp arrived the heavy volume knob was not attached and it sometimes falls off. What shall I do?
A: We ship the large volume knob separately. You can fasten it more tightly when it arrives using a few wraps of plumbers tape or super glue on the POT shaft.
Q: How many watts does the amp draw when there is no music flowing or the volume is turned way down?
A: These little guys are dainty sippers, which is why we call it "EcoAudio." Consumption varies with the power supply used:
24V/65W supply -- 6W
30V/90W supply -- 9W
30V/130W supply -- 12W
Q: Can I connect this amp directly to my computer?
A: You can absolutely hook up the amplifier to the stereo mini-jack or RCA jacks from your sound card. No USB input is supported (through an internal DAC), for now. However, you may be pleasantly surprised with the output from your sound card. Technology has advanced significantly.
Q: Can I start with the standard power supply and upgrade it later?
A: Absolutely, no problem. Just make sure you donít go over 32v on Sensation.
Q: Do you recommend batteries?
A: Battery power can be used and is highly recommended. The amp will play with any voltage between 16v and 30v.
Q: How do I restrict bass to my small satellite speakers if I am using the full range sub out to drive a powered sub?
A. Two input caps are inside the unit and an 80hz high-pass filter may be implemented with a jumper.
If you want to buy your own and replace our stock capacitors, for 80Hz they need to be .1uf
For 100Hz they need to be .082uf
For 120Hz they need to be .068uf
For 160Hz they need to be .05uf
We recommend 5% 200V Auricaps from Audience for this. Change one at a time
and the black lead goes to the volume control.
After changing the caps set the sub control to the same frequency and adjust
the bass level using several different disks as the bass level varies a lot
Q: Is the 30 day money back offer applicable to international customers?
A: We will refund your money within 30 days of delivery if the unit is in resalable condition or broken due to a fault of ours. If the unit is found to be defective and you want a replacement, we will send you a new one at no charge (including shipping).
Q: I heard such great things about the amp but it just doesn't have the bottom end of my $10,000 amplifier. What's wrong?
A: For the best bass, we recommend using a 10A linear power supply or batteries. The 30v/130w power supply is also quite powerful, delivering 4.3 amps on demand.
Q: Should I lower the volume when I turn on the unit?
A: This is a best practice with all audio amplifiers. "Cold" starting a unit with a high-level input system will reduce the overall lifespan of your unit.
Q: My speakers are 99db sensitive. Will the amp work well?
A: We have many satisfied customers driving VERY sensitive and wonderful speakers including superb, hand-made units by Robin Wyatt and Ed Schilling. If you put your ear right up to the speaker, you may notice a slight hiss, but compared to other amplifiers, you will find these units very quiet. There is one issue and that is you will find the subwoofer gain quite low compared to speaker output in such situations. You will need to turn your subwoofer way up. Battery supplies will "blacken" the background on these amps.
Q: I'm looking for a high value 2+1 speaker setup. What do you recommend?
A: There are lots of great products on the market and choice of speakers is especially subjective: intelligent people disagree about what sounds best. We're suckers for value and our customers have suggested these speakers costing less than $1,000: Occam Audio, AudioEngine (passives coming soon), AV123, Orb Audio, Aperion Audio, Ascend Acoustics, and Silverline. Parts Express also makes very high-value subs worth considering. Just note that these amps are so good that they are a perfect fit for industry ringers like Mark and Daniel and Audience. Go nuts and if you have had good luck with other speaker vendors, send us more info.
Q: I need 3 (or more inputs). Should I buy a separate pre-amp/switcher?
A: Sensation has this feature, as well as a remote control. Buy it if you can afford it! If you'd like a passive solution, consider a simple 3-1 or 5-1 RCA switcher from eBay for under $30. At a minimum, this approach will buy you time until you find the right switcher/pre-amp.
Q: Why are you using an obsolete technology made by a defunct company, Tripath?
A: The Tripath chips we use are amazing and will function properly for longer than we will live. If every man, woman, and child who subscribes to Stereophile magazine bought a Virtue ONE (which would be nice), we wouldn't run out of chips. Tripath, we forgive you for your sins and hereby immortalize you in your after-life. Long live Tripath.
Q: What is Tellurium and why do you use it on the connectors for the Sensation M901?
A: If we made the connectors from 100% copper, they would be too soft to be machined (stamping is OK) and would tarnish over time. By adding 1% Tellurium we preserve 99% of the conductivity of copper and give the part nearly the same machineability as brass, which is 30% zinc (boo, hiss). Tellurium copper is very expensive and hard to find. We may change the mixture in the future but we'll always try to offer a "no-compromise" version of the Propeller Post because otherwise our most critical customers will insist on upgrading the binding posts. We would hate that becausing buying a Virtue amp should be a "no-regret" decision. Incidentally, both the t-copper and brass versions are gold-plated so unless you cut them to see the metal underneath (copper is reddish, brass is gold-colored), they will look the same.
