Seymour AV Ice Block 5001 Introduction

SAV_front.JPGMuch of what I found on the Seymour AV website was laced with a sort of sarcastic, dry humor but their 'About' page was the best (take a good look at the picture) -

Seymour AV was founded to bring unique audiophile-focused solutions with premium components to the audio/video market at factory-direct prices. We focus on delivering top quality bang for the buck by minimizing or eliminating the overhead you, the customer, aren't interested in paying us for, like chairs or water (update: we just purchased a chair but we had a coupon). We quickly answer questions and send samples. If it's not what you expected, we'll do what it takes to make it perfect. Don't worry about being less than smiling from your purchase. We’ll treat you like you’re our only customer, just not in a desperate, creepy kind of way.

Listeners of AV Rant know that I like to interact with manufacturers stealthily. I often call customer support to get help rather than our press/review contact to get the "real deal" about their customer service. If I don't tell them I'm reviewing their product (even if I do, they don't usually believe me thinking I'm just trying to get preferential treatment), I can report on how they treat Joe Consumer - not how they treat Tom the Reviewer.

I'm not going to pull punches with this review - I had problems with the Seymour AV 5001 Monoblock. I sent my review samples back. I told Chris Seymour (owner/operator/customer service rep) I didn't want to do the review. I told him (at one point) that he should just send it to someone else as my review will detail exactly every problem I had. He wouldn't relent. He wanted a review and he wanted it from me (oh, if only my wife felt the same way). If you want to skip to the good bits, hit the set-up page. But before you do, realize what this means. Seymour AV is not afraid of a little criticism. Seymour AV is not afraid of a reviewer known to be… harsh (I say honest but whatever). Most of all, Seymour AV is not afraid to have his amps put through the ringer. Well, they didn't come out without a blemish but they did shine.

Just read through the review here again today….

and it's strange to me, if this amp is so darn good
Why does it only get 4 start in performance figure?

Please, measure these modules already!
I'd like to see real world measurements so I can finally decide ICEPower yes or no.

We you able to measure the power output w/ graphs/charts?

You know the usual RMS Continuous power rating @ 0.1% THD?

no, but I know how to interpret a data sheet. Also there is no such thing as RMS power

what do these 1000ASP modules put out at 2 ohm loads?

Very similar to the 4 ohm rating at 1kHz and likely less at higher frequencies. Most speakers impedance magnitudes are above 2 ohms so it shouldn't be much of an issue unless you trying to drive a highly reactive ESL type speaker which B&O cautions against.
