Your Ayre V-5xe has an input impedance of 100Kohms, so matching it with about any preamp on the market should not be a problem.
If you can wait, I am sure one will be available in the near future.
One just sold here on Agon recently.
There is one on Ebay, but not MP.
And, no you don't have to get matching amp and pre. I wish I could suggest a comparable preamp, but I haven't used much other than McCormack and Atma-Sphere. The former, a McC RLD-1 is available for less than $1k and can be upgraded by SMc Audio, which might be a way to go. The Atma's are quite a bit more, unfortunately, and are a tube design.
Perhaps a PS Audio?
Though, in my opinion, I would wait for an Ayre to come up for sale.
@audioconnection and @gdnrbob Thank you!
Yeah... I missed that k-5xeMP here a few days ago at a great price. The guy did not even know it was MP version.... by the time I checked and confirmed with Ayre on serial number, it was gone.
The one on eBay is “x” version, not even “xe”.
If I went with PS Audio, it would have to be the BHK Signature Preamp, but that is above my budget new, and possibly used from what I can see via hi-fi shark.
Bottom line, as you guys suggested, it may be worth waiting for the Ayre to come up for sale used, although patience is not a virtue I have 😉
Well the K-1xe was Ayre's top of the line preamp, introduced in 2002 (xe version), list at $6,750.
The K-5xe was the Ayre's entry level preamp introduced in 2003 list of $2,950.
At that time the K-3xe represented the middle of the Ayre preamp line, released in 2002, listed at $3,700.
The Ayre K-5xe MP was released in 2008, and listed at $3,500.
That's about as much as I know about the Ayre lineage.
Personally, I am a fan of tubed preamps. If I had to go with a SS preamp, I would probably look for a Klyne preamp. YMMV.
((((Yeah... I missed that k-5xeMP here a few days ago at a great price. The guy did not even know it was MP version.... by the time I checked and confirmed with Ayre on serial number, it was gone.)))
You're about to blow it again
(((The one on eBay is “x” version, not even “xe”.)))
Its still a killer unit and matches your amp can upgrade with Ayre later use w seller as a bargaining chip.
Its sure seems hard for you to see the big picture.
Sorry but you will thank me later
The only thing you have to match is the output impedence of the pre-amp with the input impedence of the power amp. The input impedence of the power amp needs to be at least ten times the output impedence of the pre-amp. The ratio can be higher, e.g. 11:1 or 15:1, but not lower e.g. 8-1, otherwise signal loss and noise may be present.
For example, a pre-amp with an output impedence of 1k ohms needs a pre-amp with an input impedence of at least 10k ohms
The only thing you have to match is the output impedence of the pre-amp with the input impedence of the power amp.
Since he is matching an Ayre preamp with an Ayre amp, I don't think there should be any impedance mismatch.
Another K-5xe MP preamp just posted today, at an even lower price.
Next thing you know there will be a thread titled "Why so many Ayre K-5xe MP preamps for sale?".
Mixing and matching is not a problem UNLESS you're talking about tubes and solid-state. There's a huge impedance difference between a tube pre-amp's output and a sand amp's inputs. It *can* be corrected by re-capping the tube pre-amp but IMHO not worth the hassle. Pardon a bit of thread drift here, but IMHO far too much attention is paid to the amp's specs, while the pre-amp, which really provides flavour to the sound, is oft overlooked as a mere switching device. It's not.
OP here, posting an update on my new addition- the Ayre k-1xe Preamp to complement my Ayre v-5xe amp.
Until now, I was going direct fro DAC (PS Audio Directstream) to Amp.
I am so happy with my new Preamp!
Weird to explain. It should not be better than direct to amp. But it is. I would explain it as much more “musical”. More “real life”. And no, I don’t think I am losing any detail or resolution.
I also think that my k-1 is better than the k-5xeMP that a friend brought over for me to audition prior to my purchase. That one had a bit more “meat” but was not so sweet and so musical.
I know here is very lengthy thread over at computer Audiophile forums on direct to amp vs. using preamp, and to me, using this Preamp improved thing hands down. No question about it
No, you don't have to match brands as long as there are no impedance mismatches. I just traded in a Cary CAD 120's hooked up to a Cary SLP 98P pre for a pair of Canary M350 monoblocks and my Legacy Whispers HD never sounded so great, and they were excellent with the Cary too. My neighbors know who Johnny Winter is now.
